Procedure

Sodium hydride (60%/mineral oil: 81 mg) was dissolved in dimethylformamide (5 mL), and the solution was cooled to 0° C. After addition of 4-nitroindole (300 mg), the mixture was stirred for one hour, and bromoacetic acid ethyl ester (340 mg) was added thereto, followed by stirring at 0° C. for 4 hours. Water was added thereto and the mixture was concentrated, diluted with ethyl acetate, washed with water, dried over sodium sulfate, then concentrated to give the title compound (367 mg)
