실험 절차

To a mixture of 3-bromo-1-(3-fluoro-4-methylbenzyl)pyrrolidin-2-one (0.51 g, 1.8 mmol, Intermediate 6) and 4-(4-(benzyloxy)phenyl)-3,3-difluoropiperidine (0.3 g, 1 mmol, from step C) was added triethylamine (0.69 mL, 4.9 mmol) and the resulting mixture was heated in a sealed tube at 120° C. for 1 h. The reaction mixture was allowed to cool and then diluted with water and the mixture was extracted with ethyl acetate. The organic layer was separated, washed with brine, dried over Na2SO4, filtered, and concentrated. The residue (0.45 grams, 64%, mixture of 4 diastereoisomers) was used directly in the next step without further purification, LCMS (method P) RT 1.19 min, m/z 509 (M+H+).
