Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 5-Methyl-2-(piperazin-1-yl)thiazole | HCID 21100190 | — |
| Reactant | 2-Isopropoxy-5-methylsulfonylbenzoic acid | HCID 21100237 | — |
| Product | (2-Isopropoxy-5-methanesulfonyl-phenyl)-[4-(5-methyl-thiazol-2-yl)-piperazin-1-yl]-methanone | HCID 21100245 | 75% |
Reaction Steps
Prepared in analogy to example 1 (b) from 2-isopropoxy-5-methanesulfonyl-benzoic acid (Example A1) and 1-(5-methyl-thiazol-2-yl)-piperazine. The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) to yield the title compound as an off-white foam (yield 75%). MS (m/e): 424.3 (M+H+, 100%).
