To a solution of (3R)-3-amino-1-(4-chlorophenyl)pyrrolidin-2-one as prepared in Example 14 (0.08 g) in EtOH (3 ml) was added 1-[(2R)-2-hydroxy-3-(2-methylbenzothiazol-5-yloxy)propyl]piperidin-4-one as prepared in Example 13 (0.15 g, 0.53 mmol) and sodium triacetoxyborohydride (0.112 g, 0.53 mmol). The reaction was stirred at room temperature for 48 hours. The solvent was removed and the residue purified using preparative TLC (10:1 DCM:MeOH) to yield (3R)-3-({1-[(2R)-2-hydroxy-3-(2-methylbenzothiazol-5-yloxy)propyl](4-piperidyl)}amino)-1-(4-chlorophenyl)pyrrolidin-2-one.
