Dimethylamine → 3-(2-Chloro-6-methylphenoxy)-N,N-dimethyl-1-azetidinecarboxamide

Participants

Reaction Steps

A stirred solution of 3.9 g (0.015 mole) of 3-(2-chloro-6-methylphenoxy)-1-azetidinecarbonyl chloride in 20 mL of tetrahydrofuran was treated all at once with 5.1 mL (0.045 mole) of 40% aqueous dimethylamine. After stirring for 72 h the raction mixture was diluted with 200 mL of water and the oil which separated was extracted into methylene chloride (3×30 mL). The combined extracts were dried by filtering through Whatman PS paper and concentrated in vacuo (3.6 g). The crude oil solidified when cooled in a dry ice/acetone bath and was recrystallized from ethyl ether in a dry ice-acetone bath yielding, after filtering cold, 2.6 g (64.5%) of coarse white crystals, mp 46°-47° C.
