Procedure
Boc-(R)-1,2 diamino-1-phenylethane (prepared by the method of O'Brien, P. et al. J. Med. Chem. 37 (1994) 12, 1810-1822) (0.3 g, 1.27 mmol.), phthalic anhydride (0.2 g., 1.4 mmol.) and TEA (0.1 ml) were dissolved in chloroform (20 ml.) and stirred under reflux for 2 days. The reaction mixture was then washed with 10% hydrochloric acid, 2M sodium hydroxide solution and brine, dried over magnesium sulphate, filtered and evaporated to give the product. The above product was further elaborated by Method 4 to the title compound.
