Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1-(4-Methyl-1,3-thiazol-2-yl)piperazine | HCID 14479872 | — |
| Reactant | 2-Isopropoxy-5-methylsulfonylbenzoic acid | HCID 21100237 | — |
| Product | (2-Isopropoxy-5-methanesulfonyl-phenyl)-[4-(4-methyl-thiazol-2-yl)-piperazin-1-yl]-methanone | HCID 21100240 | 87% |
Reaction Steps
Prepared in analogy to example 1 (b) from 2-isopropoxy-5-methanesulfonyl-benzoic acid (Example A1) and 1-(4-methyl-thiazol-2-yl)-piperazine. The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) to yield the title compound as an amorphous yellow solid (yield 87%). MS (m/e): 424.1 (M+H+, 100%).
