Methylamine → 3-(2-Chloro-6-methyphenoxy)-N-methyl-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 3.5 mL (0.045 mole) of 40% aqueous monomethylamine. After stirring for 72 h the reaction mixture was diluted with 200 mL of water and the precipitated solid collected by filtration to give 5.6 g of wet white product. The crude product was recrystallized (after drying) from benzene/ligroin, yielding 2.9 g (75.9%) of white crystalline product, mp 119°-121° C.
