soluble, and is crystallizable in this solvent to yield "beautiful, compact, clear, on sixsided cut-crystal plates

that melt with decomposition at 235-240° C." This is obviously the way to go. The hydrazide should be recrystallized from absolute ethanol,

and then dried under a vacuum to remove residual alcohol clinging to the crystals. About 300 ml of hot ethanol is required to dissolve each gram of lysergic acid hydrazide during the crystallization. Upon cooling, a first crop of pure lysergic acid hydrazide is obtained. Then, by boiling away half of the mother liquor and cooling, an additional crop is obtained. This process can be continued as long as the crystals obtained look nice. Practical LSD Manufacture 28 Step Two: Lysergic Acid Pyrazole In this reaction, one mole of lysergic acid hydrazide is dissolved in an inert, water-miscible solvent like ethanol. Then an excess of 1-molar hydrochloric acid is added to form a salt with the lysergic acid hydrazide. To this mixture is then added two moles of acetylacetone (2,4-pentanedione), which forms the desired pyrazole. This reaction is not nearly as touchy as beaver bong prices the formation of the hydrazide. The presence of traces of moisture from the air poses no problem.
2,4-pentanedione finds use in analytical chemistry as a chelating agent for transition metals, and as such should be available without raising too many red flags. Synthesis of this compound is not hard, and directions for doing so are found in US Patents 2,737,528 and 2,834,811. To do the reaction, the flask containing the 5 grams of hydrazide is wrapped in a single layer of foil to exclude light.
Then a magnetic stirring bar is added, along with 18 Zongs For Sale ml of ethanol, 18 ml water, 20 ml 1- molar HC1 (made by adding one part 37% HC1 to 11 parts water) and this mixture is stirred for a few minutes.
Then 3.5 grams (3.5 ml) of 2,4-pentanedione is added at room temperature, and the stirring continued for an hour or so. The product is recovered from solution by the slow addition with stirring of 20 ml 1-molar NaOH (40 grams per liter). This neutralization throws

the pyrazole out of solution as a solid. The solid is collected by filtration through a Buchner funnel, and rinsed off with 4 LSD Directly From The Lysergic Amides — The One Pot Shot 29 some water. The crystals are then dried under a vacuum, preferably with the temperature elevated to 60° C. Further purification can be done by crystallization. If so desired, dissolve the crystals in chloroform, then add 8-10 volumes of ether to precipitate the product. I do not feel this is necessary if the hydrazide used was reasonably pure, since all the reagents used in the last step are soluble in water. The water rinse should have carried them away. Further, alcohol and 2,4-pentanedione are volatile, amsterdam bongbastic and would be removed in the vacuum drying. Step Three: LSD CH, This simple and easy reaction is done as follows: In a flask wrapped in a single layer of foil
