実験手順

(3R,10S)-5-Methyl-3-(9-oxo-1,8-diazatricyclo[10.6.1.013,18 ]-nonadeca-12(19),13(18),14,16-tetraen-10-ylcarbamoyl)hexanoic acid (183 mg) was taken up in 40 mL of dry CH2Cl2 and at 0° C. ethanol (0.5 mL, 5 eq) was added followed by N,N-dimethylaminopyridine (0.1 eq, 5 mg) and finally EDCI (209 mg, 5 eq). The resulting solution was stirred from 0° C. to room temperature overnight. Additional CH2Cl2 (100 mL) was added and the mixture was washed with 0.5N HCl (2×50 mL), saturated NaHCO3 (2×50 mL) and finally with brine (1×50 mL). The organic layer was dried over Na2SO4, filtered and evaporated to dryness. Recrystallization from ethyl acetate and petroleum ether gave (3R,10S)-5-Methyl-3-(9-oxo-1,8-diaza-tricyclo[10.6.1.013,18 ]nonadeca-12(19),13(18),14,16-tetraen-10-ylcarbamoyl)hexanoic acid ethyl ester as a white solid (Yield: 108 mg, 55%), MS: 470 (M+H)+.
