실험 절차
386 mg of 3-nitrophthalic anhydride and 242 mg of (R)-α-methylbenzylamine were charged in an egg-plant type flask of 50 ml, followed by stirring under heating at a temperature of 180° C. for 1.5 hours. After cooled, the reaction product was dissolved in chloroform, purified by silica gel column chromatography (eluent; methylene chloride:methanol=30:1 v/v), recrystallized from a mixed solvent of n-hexane-ethyl acetate, to obtain 430 mg of the desired product as a light yellow powder. Yield: 73%. m.p. 115-117° C.; MS(EI+) 296(M)+
