反応手順

A solution of (6) at 0° C. (3.43 g; 0.012 mmol) in methanol (40 ml) was treated with 2N sodium hydroxide (6.9 ml; 0.013 mmol). The mixture was stirred at ambient temperature for 90 minutes. After evaporation of the methanol and removal of the insoluble material by filtration, the solution was adjusted to pH5 with 6N hydrochloric acid. The mixture was extracted with dichloromethane and the organic layer evaporated to dryness to give 3-[(2-tertbutoxycarbonylaminoacetyl)amino]propanoic acid (7).
