실험 절차
tent-Butyl 2-(4-(4-(4-chlorophenethylcarbamoyl)phenoxy)-3-cyanophenyl)acetate (0.400 g) and 4-methylbenzenesulfonyl azide (0.193 g) were dissolved in 5 ml of acetonitrile and treated with DBU (0.152 ml). The reaction was stirred for 4 hours, then concentrated, diluted with ethyl acetate and washed with water. The organic layer was dried, filtered, concentrated onto silica gel and purified by silica gel chromatography to provide tert-butyl 2-(4-(4-(4-chlorophenethylcarbamoyl)phenoxy)-3-cyanophenyl)-2-diazoacetate (0.48 g) as a bright yellow solid.
