Reaction Conditions

Reaction Steps

To a stirred solution of 1-methyl-2-(methylaminomethyl)-1H-indole (1.0 g, 5.7 mmole), from Preparation 1, and Et3N (0.9 mL, 6.4 mmole) in CH2Cl2 (50 mL) at 0° C. was added dropwise acryloyl chloride (0.51 mL, 6 mmole) over 5 minutes. The reaction was stirred at 0° C. for 1 hr, then was poured into ice water. The organic phase was separated, washed with brine, dried (MgSO4), and concentrated to dryness to give the title compound (1.19 g, 91%) as a yellow oil. This was used without further purification: TLC (silica gel, 50% EtOAc/hexanes) Rf=0.31.
