実験手順

To a stirred solution of the mixture of 2-(3-(S)-methoxymethoxypyrrolidin-1-yl)-1-(S)-phenylethanol and 2-(3-(S)-methoxymethoxypyrrolidin-1-yl)-2-(R)-phenylethanol (251 mg, 1.00 mmol) and triethylamine (0.167 ml, 1.20 mmol) in CH2Cl2 (4 ml) was added methanesulfonyl chloride (0.093 ml, 1.20 mmol) dropwise at 0° C. (ice bath). After 15.5 h stirring at room temperature, the reaction mixture was washed with saturated NaHCO3 aqueous solution, brine, dried (Na2SO4), and concentrated to give 238 mg of brown viscous oil-(i). To a suspension of NaH (48 mg, 1.20 mmol) in N,N-dimethylformamide (2 ml) was added a solution of 3-chloro-4-methylaminobenzonitrile (200 mg, 1.20 mmol) at room temperature. After stirring for 45 min, to this mixture was added a solution of the above brown viscous oil-(i) in N,N-dimethylformamide (2 ml) at room temperature and the mixture was stirred at room temperature for 4.5 h. H2O was added to this mixture, basified with 25%-NH4OH and extracted with CH2Cl2. The extract was washed with water, brine, dried (Na2SO4), and concentrated to give brown oil, which was purified by column chromatography (silica gel; 20 g, CH2Cl2/MeOH: 100/1-50/1) to afford 244 mg (61%) of brown oil.
