実験手順

A solution of 2-(4-aminophenyl)-6-ethoxy-1-ethyl-1H-indole-3-carbonitrile (319 mg, 1.04 mmol) in 1,4-dioxane (3 mL) is treated with chloroacetyl isocyanate (0.10 mL, 1.17 mmol), and the resulting solution is warmed to 60° C. overnight. The solution is cooled, and DBU (0.20 mL, 1.31 mmol) is added. This mixture is stirred at ambient temperature overnight, and then is partitioned between water and ethyl acetate (50 mL each). The organic layer is washed with saturated brine, and then dried over anhydrous magnesium sulfate, filtered and evaporated. The residual material is triturated with ether, and the resulting solid is collected by filtration and dried under high vacuum to afford the title product (319 mg, 0.821 mmol, 79%).
