A solution of glycolic acid (100 mg) in DMF (2 ml) was added dropwise to a solution of 2-methyl-4-({5-[2-(methylamino)ethoxy]quinazolin-4-yl}amino)phenol (400 mg) in DMF (4 ml) and the mixture held under sonication for 5 minutes. A solution of HATU (519 mg) in DMF (2 ml) was then added and the solution was stirred at ambient temperature for 16 hours, and then concentrated in vacuo. The residue was treated with water to precipitate a brown solid that was collected by filtration, and washed with water to give 2-hydroxy-N-[2-({4-[4-hydroxy-3-methylanilino]quinazolin-5-yl}oxy)ethyl]-N-methylacetamide as a brown solid (406 mg, 86%); NMR spectrum (DMSO-d6) 2.15 (s, 3H), 2.94 (s, 3H), 3.87 (m, 2H), 4.04 (s, 2H), 4.48 (m, 2H), 6.81 (d, 1H), 7.20 (dd, 1H), 7.25 (d, 1H), 7.35 (m, 2H), 7.92 (t, 1H), 8.64 (s, 1H), 9.46 (s, 1H), 10.49 (s, 1H); Mass spectrum M+ 383.
