実験手順

To a cooled (15° C.) and stirred solution of tin (II) chloride (0.37 g, 1.65 mmol) and con. hydrochloric acid (2.0 mL) was added a solution of 2-(4-methoxyphenoxymethyl)-6-nitrobenzonitrile (100.0 mg, 0.35 mmol). The reaction mixture was slowly warmed to room temperature and stirred for 3 hours. The reaction mixture was poured on to crushed-ice and potassium hydroxide solution, stirred, extracted with dichloromethane, filtered and dried. Purification by silica gel chromatography (1% methanol in dichloromethane) yielded 65 mg of 2-amino-6-(4-methoxyphenoxymethyl)benzonitrile.
