実験手順

To 3.41 g of 2-(4-methoxy-benzyl)-2,8-diaza-spiro[4.5]decan-1-one hydrochloride (12.3 mmol) in dichloromethane (50 mL) was added triethylamine (1.71 mL, 12.3 mmol) followed by 3.85 g of (3R,4S)-3-formyl-4-phenyl-pyrrolidine-1-carboxylic acid tert-butyl ester (12.3 mmol) in dichloromethane (75 mL) and stirred for 1 h at room temperature. Sodium triacetoxyborohydride (3.91 g, 18.4 mmol) was then added and the reaction mixture stirred overnight at room temperature.
