Benzylamine → HCID 21195959, compound

Participants

Reaction Steps

A solution of benzylamine (0.98 ml, 8.93 mmol) was added to a solution of 4-(2-fluoro-5-bromobenzyloxy)but-2-ynyl bromide (300 mg, 0.893 mmol) in tetrahydrofuran (4.5 ml). The cloudy reaction mixture was stirred for about twenty hours, at which time no starting material remained, as determined by thin layer chromatography. The solvents were removed in vacuo. The residue was taken up in methylene chloride and washed with 1 M potassium carbonate. The aqueous phase was back extracted with methylene chloride (2×15 ml). The organic fractions were combined, and dried over sodium sulfate. The solvents were removed in vacuo. The resulting oil was further purified by flash chromatography, affording 200 mg (62%) of the title intermediate.
