Procedure

To a solution of 6-bromo-2-(ethylamino)-4-methylpyrido[2,3-d]pyrimidin-7(8H)-one (100 mg, 0.35 mmol) in DMF (2 mL), prepared using procedures analogous to those described in Example 14, was added NaH (30 mg, 60%, 0.7 mmol). The mixture was stirred for 30 min at room temperature and was warmed to 70° C. 3-Bromopropanol (48 mg, 0.35 mmol) was then added. The stirring was continued for 12 h. Standard workup and purification by column chromatography gave 33 mg (27% yield) of 6-bromo-2-(ethylamino)-8-(3-hydroxypropyl)-4-methylpyrido[2,3-d]pyrimidin-7(8H)-one. 1H NMR (400 MHz, CDCl3) δ 8.13 (s, 1H), 5.42 (br s, 1H), 4.59 (br s, 2H), 3.50-3.47 (m, 5H), 2.55 (s, 3H), 2.02 (br s, 2H), 1.28 (t, 3H); MS (EI) for C13H17BrN4O2: 341 (MH+).
