Reaction Steps

To a solution of tert-butyl 2-methyl-1H-indole-3-carboxylate (300 mg, 1.30 mmol) in N,N-dimethylformamide (10 mL) was added sodium hydride (103.76 mg, 2.59 mmol, 60%). The mixture was stirred at 0° C. for 30 minutes. Then 3-methylbutanoyl chloride (234.60 mg, 1.95 mmol) was added at 0° C. and the mixture was stirred at room temperature (25° C.) for 2 hours. The mixture was cooled with ice, quenched with water (5 mL), diluted with ethyl acetate (20 mL), washed with brine (20 mL), extracted with ethyl acetate three times (20 mL×3), then dried over sodium sulfate. After concentration, the residue was purified by column on silica gel (0%-5% PE/EA) to afford the title compound (200 mg, yield: 48.89%).
