1-(5-Trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazine trifluoroacetate → [5-Methanesulfonyl-2-(2,2,3,3,3-pentafluoro-propoxy)-phenyl]-[4-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazin-1-yl]-methanone

Participants

Reaction Steps

Prepared in analogy to example 1 (b) from 5-methanesulfonyl-2-(2,2,3,3,3-pentafluoro-propoxy)-benzoic acid (Example A30) and 1-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazine trifluoroacetate (Example 62(b)). The crude material was purified by chromatography (SiO2, methanol/dichloromethane) to yield the title compound as an off-white solid (yield 56%). MS (m/e): 569.3 (M+H+, 100%).
