실험 절차

A stirred solution of with ethyl (R) 3-(4-aminophenyl)butanoate (0.107 g, Reference Example 1) in dimethylformamide (10 mL) was treated with diisopropylethylamine (0.4 g), 2-(4-methoxy-2-o-tolylaminobenzoxazol-6-yl)acetic acid [0.105 g, Reference Example 9(a)] and then with O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (0.14 g). The mixture was left to stand for 20 hours and then partitioned between ethyl acetate and hydrochloric acid (1M). The organic phase was washed with water, then with aqueous bicarbonate solution (5%), then with water, then with brine, then dried and then evaporated to give the title compound (0.17 g) as a cream coloured solid.
