N-methyl-2-pyrrolidone → HCID 21071658, compound

Participants

Reaction Steps

Combine N-methyl-N-(2-(6-fluoro-1-methyl-1H-indol-3-yl)ethylamine (0.2 mmol) in 1-methyl-2-pyrrolidinone (0.5 mL) and 3-propyloxybenzaldehyde (0.32 mmol) in dichloromethane (1 mL) and rotate. After overnight rotation, add sodium borohydride (1.0 mmol) as a stock solution in 1-methyl-2-pyrrolidinone (0.5 mL) and rotate. After rotation for 3 h, dilute the reaction mixture with 1 mL of 10% acetic acid/methanol, and directly apply the resulting solution to a 2 g SCX column. After thoroughly washing with methanol, elute the column with 2 M ammonia-methanol and concentrate the eluent to a residue, which was further purified by Gilson UV prep system.
