To a mixture of 4-(2-methoxyphenyl)piperidine (0.951 g, 4.97 mmol) and (3S,7aR)-7a-cyclopropyl-3-phenyl-2,3-dihydropyrrolo[2,1-b]oxazol-5(7aH)-one (preparation #24) (1.0 g, 4.1 mmol) was added water (0.8 mL, 44 mmol). After about 5 minutes, DCM (5 mL) was added. All the solids dissolved. The reaction mixture was stirred at room temperature for about 16 hours. Purification on a Biotage silica gel column eluting with DCM/EtOAc (1:0 to 1:1) afforded (3S,7R,7aR)-7a-cyclopropyl-7-(4-(2-methoxyphenyl)piperidin-1-yl)-3-phenyltetrahydropyrrolo[2,1-b]oxazol-5(6H)-one (1.29 g, 2.98 mmol) as a white solid. RP-HPLC (Table 1, Method a) Rt 2.14 min; m/z: (M+H)+ 433.
