Participants

Reaction Steps

HATU (0.24 g) was added to a solution of N-(3-chloro-2-fluorophenyl)-6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-amine dihydrochloride (250 mg), diisopropylethylamine (0.37 ml) and methoxyacetic acid (0.054 g) in methylene chloride (9 ml) and the mixture was stirred at room temperature for 2.5 hours. Methylene chloride (20 ml) was added and the organic layer was washed with aqueous sodium hydroxide (2M, 30 ml) and water (30 ml). The resulting product was purified by flash column chromatography eluting with methanol (3%) and methylene chloride (97%) to give a foam. This was re-precipitated by stirring in diethyl ether (20 ml) to give the title product as a white solid (0.200 g); 1H N Spectrum: (DMSO d6 373K) 1.73 (m, 2H), 2.02 (m, 2H), 3.37 (s, 3H), 3.41 (m, 2H), 3.77 (m, 2H), 3.98 (s, 3H), 4.09 (s, 2H), 4.85 (m, 1H), 7.26 (m, 1H), 7.30 (s, 1H), 7.39 (m, 1H), 7.59 (m, 1H), 7.81 (s, 1H), 8.38 (s, 1H), 9.34 (br s, 1H); Mass Spectrum: (M+H)+ 475.
