Ethyl Acrylate → HCID 59497627, compound

Participants

Reaction Steps

To a solution of 1-(5-Chloro-benzo[b]thiophen-3-ylmethyl)-1,3-dihydro-benzimidazol-2-one (50 mg, 0.16 mmol) in DMF (2 mL) were added ethyl acrylate (0.02 mL) and benzyltrimethyl ammonium hydroxide (20 mg, 0.01 mmol). The resulting mixture was stirred at room temperature overnight. When the reaction was complete, the reaction mixture was diluted with ethyl acetate and washed with water (×4). The organic phase was dried over Na2SO4 and concentrated. The resulting residue was purified by silica gel prep TLC using 95:5 CH2Cl2:MeOH as an eluent to afford 50 mg of the desired product as a colorless oil. LCMS (ESMS): m/z 415.78 (M+H+).
