HCID 21100320HCID 21100320, compoundYield 71%

Procedure

Prepared in analogy to example 1 (b) from 5-methanesulfonyl-2-morpholin-4-yl-benzoic acid (Example A13) and 1-(5-trifluoromethyl-thiazol-2-yl)-piperazine hydrochloride (Example 58(c)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) followed by trituration in pentane to yield the title compound as an off-white crystalline solid (yield 71%). MS (m/e): 505.3 (M+H+, 100%).
