Synthese
A suspension of N'-[(2Z)-Piperazin-2-ylidene]trifluoroacetohydrazide (27.3 g, 0.13 mol) in 110 mL of methanol was WARMED TO 55 ℃. 37% Hydrochloric acid (11.2 mL, 0.14 mol) was added over 15 min at this temperature. During the addition, all solids dissolved, resulting in a clear solution. The reaction was aged for 30 min. The solution was cooled to 20 ℃ and aged at this temperature until a seed bed formed (10 min to 1 h). 300 ML of MTBE was charged at 20 ℃ over 1 h. The resulting slurry was cooled to 2 ℃, aged for 30 min and filtered. Solids were washed with 50 mL of ethanol: MTBE (1: 3) and dried under vacuum at 45 ℃. Yield of 3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride was 26.7 g (99.5 area wt% pure by HPLC).
