Product 1

HCID 11641622HCID 11641622, compoundYield 69%

Procedure

Prepared in analogy to example 1 (b) from 2-isopropoxy-5-methanesulfonyl-benzoic acid (Example A1) and 3-phenyl-5-piperazino-1,2,4-thiadiazole. The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) to yield the title compound as a white crystalline solid (yield 69%). MS (m/e): 487.3 (M+H+, 100%).
