Methylamine → HCID 15053461, compound

Participants

Reaction Steps

A solution of 4.8 g (0.02 mole) of 3-(3-methoxyphenoxy)-1-azetidinecarbonyl chloride in 20 ml of tetrahydrofuran was treated with 4.7 g (0.06 mole) of 40% aqueous monomethylamine and stirred for 16 hr. The reaction mixture was diluted with 200 ml of water and the oil which separated was extracted into methylene chloride (2×50 ml). The extracts were dried by passing through Whatman phase separating paper and concentrated in vacuo (3.85 g). The residue was purified by chromatography on two 4 mm (silica gel) chromatotron plates by eluting with an ethyl acetate/methylene chloride gradient to give 0.98 g (21%) of tan solid. Recrystallization from benzene with a trace of ligroin yielded 600 mg of tan crystalline powder, m.p. 109°-111° C.
