Reaktionsschritte

To a solution of 0.023 g (0.071 mmol) of 3-(SR)-(4-phenylpiperidinylmethyl)-4-(RS)-(3-thienyl)pyrrolidine and 0.079 mL of Et3N in 2 mL of CH2Cl2 was added 0.059 g (0.28 mmol) of 3,4-difluorobenzoyl chloride and the reaction mixture was stilled for 0.5 h. The reaction mixture was partitioned between CH2Cl2 and sat'd NaHCO3 solution. The organic fraction was dried over Na2SO4, filtered and the filtrate was concentrated. The residue was purified by chomatography (silica, acetone: hexanes, 1:3) to give 0.026 g of the title compound. 1H NMR (CDCl3) δ7.17-7.49 (m, 9H), 7.13 and 7.08 (s, 1H), 7.04 and 6.99 (d, 1H, J=4.6 Hz),4.08-4.15 (m, 2H); Mass Spectrum (CI) m/e=482 (M+1).
