Procedure

1-(2-Benzothiazol-2-ylmethylpiperidin-1-yl)-2,2,2-trifluoroethanone, D29 (1.2 g) was dissolved in methanol (40 ml) and 2N sodium hydroxide solution (20 ml) and heated to 50° C. for 0.75 h. After cooling, the reaction solution was partitioned between dichloromethane and water. The organic solution was dried (MgSO4) and the solvent removed in vacuo. The residue was chromatographed (silica gel, 0-10% [9:1 MeOH/conc. ammonia solution] in dichloromethane) to afford the title compound (0.68 g).
