Cyclobutanone → N-cyclobutylidene-1-(4-methoxyphenyl)methanamine

Participants

Reaction Steps

A solution of (4-methoxyphenyl)methanamine (9.26 mL, 71.3 mmol) and cyclobutanone (5.35 mL, 71.3 mmol) in anhydrous ethyl ether (70 mL) was treated with activated 4 angstrom molecular sieves (2.5 g). The mixture was stirred vigorously for 16 hours at ambient temperature. The reaction mixture was filtered, and the sieves were washed with ethyl ether. The filtrate was concentrated under reduced pressure with no heat. The title compound was stored under nitrogen and used without further purification. MS DCI(+) m/z 190.3 [M+H]+.
