2-Piperazin-1-yl-thiazole-5-carbonitrile → 2-[4-(2-Isobutoxy-5-methanesulfonyl-benzoyl)-piperazin-1-yl]-thiazole-5-carbonitrile

Participants

Reaction Steps

Prepared in analogy to example 1 (b) from 2-isobutoxy-5-methanesulfonyl-benzoic acid (Example A8) and 2-piperazin-1-yl-thiazole-5-carbonitrile (Example 6(a)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) followed by trituration in ether to yield the title compound as a white crystalline solid (yield 61%). MS (m/e): 449.4 (M+H+, 100%).
