Reaction Steps

To a stirred solution of 5-bromo-1-{(3SR,4RS)-3-(3,4-dichloro-phenyl)-4-[(3-fluoro-4-trifluoromethyl-benzyl)-methyl-amino]-pyrrolidin-1-yl}-pentan-1-one (XV-1) (40 mg, 0.068 mmol) in DMF (2 ml) was added potassium cyanide (5.0 mg, 0.077 mmol) and 18 crown 6-ether (18 mg, 0.068 mmol). The reaction mixture was stirred at 40° C. overnight, concentrated under vacuo. The product was purified by preparation HPLC to yield 3.2 mg (9%) of the title product as a colorless oil. ES-MS m/e: 530.1 (M+H+).
