Product 1

HCID 21100230HCID 21100230, compoundYield 22%

Procedure

Prepared in analogy to example 1 (b) from 2-cyclopropylmethoxy-5-methanesulfonyl-benzoic acid (Example A5) 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 a white crystalline solid (yield 22%). MS (m/e): 490.3 (M+H+, 100%).
