Reaction Steps

A solution of 3-tert-butoxycarbonylamino-2-(pyrimidin-2-ylamino)-propionic acid methyl ester (227 mg, 0.77 mmol) in HCl/dioxane (4 N, 5 mL) was stirred at room temperature for 1 hour. The solution was then concentrated to dryness and the residue was dissolved in water (20 mL). This solution was then washed with dichloromethane (2×10 mL) and hexanes (10 mL). The solution was then filtered and lyophilized to yield (+/−)-3-amino-2-(pyrimidin-2-ylamino)-propionic acid methyl ester as a yellow solid (185 mg, 90%).
