Reaction Steps

A mixture of (5R)-5-cyanomethyl-1-(p-toluenesulfonyl)-2,3,4,5-tetrahydro-1H-benzazepine (102 mg), potassium hydroxide (84 mg) and ethylene glycol (2 ml) is heated with stirring at 170-175° C. for 6 hours. The reaction solution is acidified with conc. hydrochloric acid, extracted with ethyl acetate, dried over sodium sulfate, and the resulting residue is purified by silica gel column chromatography (solvent; dichloromethane:methanol;=9:1) to give (5R)-5-carboxymethyl-1-(p-toluenesulfonyl)-2,3,4,5-tetrahydro-1H-benzazepine (108 mg).
