Procedure

K2CO3 (15 mmol, 2.07 g) and 1-formyl-2-methyl indole (10 mmol, 1.59 g) were stirred in 50 mL DMF. t-Butyl bromoacetate (12 mmol, 1.77 mL) was added and the reaction was heated to 80° C. for 1 h. The reaction was cooled, diluted with 100 mL EtOAc, and washed with water (3×50 mL). The organic solution was dried over MgSO4 and concentrated to give the sub-title compound as a yellow solid (2.6 g).
