Procedure
Prepared in analogy to Example 4 from (4-hydroxy-piperidin-1-yl)-(2-isopropoxy-5-methanesulfonyl-phenyl)-methanone (Example 3(a)) and ethyl 4-hydroxybenzoate. The crude material was purified by reversed phase HPLC (acetonitrile/water) to yield the title compound as an amorphous white solid (yield 28%). MS (m/e): 490.5 (M+H+, 100%).
