Participants

Reaction Steps

Using an analogous procedure to that described in Example 5 N-(3-chloro-2-fluorophenyl)-6-methoxy-7-[(3S)-piperidin-3-yloxy]quinazolin-4-amine dihydrochloride (250 mg) was coupled with glycolic acid (0.045 g). 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 (0.105 g); 1H NMR Spectrum: (DMSO d6 373K) 1.59 (m, 1H), 1.87 (m, 2H), 2.09 (m, 1H), 3.40-3.60 (m, 4H), 3.86 (m, 1H), 3.98 (s, 3H), 4.044.18 (m, 2H), 4.66 (m, 1H), 7.24 (m, 1H), 7.31 (s, 1H), 7.40 (m, 1H), 7.60 (m, 1H), 7.80 (s, 1H), 8.38 (s, 1H), 9.30 (br s, 1H); Mass Spectrum: (M+H)+ 461.
