To a solution of (2-chloro-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)methyl acetate 5 (2.3 g, 7.1 mmol) in THF (50 mL) was added a 1M solution of lithium hydroxide in water (26 mL). The resulting solution was stirred at room temperature for 2 hours. The reaction mixture was diluted with water and extracted three times with dichloromethane. The combined extracts were washed with brine, dried over sodium sulfate, filtered and concentrated to give (2-chloro-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)methanol 6. LCMS (MH)+=281.1. 1H-NMR (400 MHz, CDCl3, ppm): 8.09 (1H, d, J=8.8 Hz), 7.66 (1H, d, J=8.8 Hz), 4.91 (2H, s), 4.56 (4H, br), 3.91 (4H, t), 2.86 (1H, s)
