Sodium hydride → 1-(3-Methyl-4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)imidazolidin-2-one

Participants

Reaction Steps

To a slurry of NaH (60% in mineral oil, 0.109 g, 2.73 mmol) in THF (13 mL) in a sealable tube under nitrogen was added 1-(2-chloroethyl)-3-(3-methyl-4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)urea (0.537 g, 1.30 mmol) in portions. The reaction was sealed and heated to 80 deg. C. for 3 h. The reaction was cooled to ambient temperature and was concentrated under a stream of nitrogen. The resulting solid was suspended in 50 mL water, acidified to pH 1 with 6 N HCl, and filtered. The solid was rinsed with water, diethyl ether, and dried in vacuo to give 1-(3-methyl-4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)imidazolidin-2-one as a tan solid. MS m/z=377 [M+1]+. Calc'd for C20H20N6O2: 376.16.
