Procedure
Prepared in analogy to Example 1 from 2-isopropoxy-5-methanesulfonyl-benzoic acid (Example A1) and 4-hydroxypiperidine. The crude material was purified by flash chromatography (methanol/dichloromethane) to yield the title compound as an amorphous yellow solid (yield 70%). MS (m/e): 342.3 (M+H+, 100%).
