Participants

Reaction Steps

6-Chloro-9-vinylpurine (JOC 1968, 33, 1341) (0.54 g, 3 mmol), was added to methylamine (15 mmol, 2.0M in THF) in THF (5 mL) and the mixture was stirred for 5 h at rt. Water was added to dissolve the white precipitate (methylamine hydrochloride). The aqueous layer was extracted with ethyl acetate and the combined organic layers were dried over sodium sulfate, concentrated on a rotavap, and then subjected to silica gel column chromatography (5% methanol/methylene chloride) yielding the desired product.
