Reaction Steps

2-(4-Fluoro-phenylamino)-5-(5-hydroxy-pyridin-2-yl)-3-methyl-3H-pyrimidin-4-one (2.18 g, 7 mmol) was dissolved in dry DMF (30 ml) to which was added 60% NaH (774 mg, 19.3 mmol). After the mixture was stirred at room temperature for several minutes, a suspension of 8-Chloro-[1,3]dioxolo[4,5-g]quinazoline (2.08 g, 6.7 mmol) in dry DMF (40 ml) was added. The reaction mixture was stirred at room temperature for 1-2 hrs, then diluted with EtOAc and washed with sat'd NaHCO3 (3×), H2O (1×), sat'd NaCl (1×), dried (Na2SO4), and concentrated in vacuo to give crude title compound and further purification to yield product (3.68 g, 90%). 1HNMR (400 MHz, DMSO): 9.18 (s, 1H), 8.60 (m, 3H), 8.45 (d, 1H), 7.84 (s, 1H), 7.82 (m, 1H), 7.55 (m, 3H), 7.21 (m, 2H), 4.15 (s, 2H). LC/MS Calcd for (M+H)+485.4. found 485.9.
