Reaction Steps

A mixture of 4-hydroxy-6-methyl-2-pyrone (0.9 g, 0.007 mol) and 4-amino-5-aminomethyl-2-methylpyrimidine (1.0 g, 0.007 mol) in water (10.0 ml) was heated at 100° C. for 1 h under argon atmosphere. The reaction mixture was cooled, and filtered the yellow precipitate. It was washed successively with cold water, ethanol, and dried in vacuo to afford the title compound (1.01 g, 51%) as a pale yellow powder: 1H NMR (DMSO-d6/400 MHz) δ 7.62 (s, 1H), 7.04 (s, 1H), 5.83 (d, 1H, J=2.0 Hz), 5.58 (d, 1H, J=2.0 Hz), 4.92 (s, 2H), 2.24 (s, 3H), and 2.22 (s, 3H); ES-HRMS m/z 325.0304 (M+H C12H14N4O2Br requires 325.0295). Step 2 1-[(4-amino-2-methylpyrimidin-5-yl)methyl]-3-bromo-4-hydroxy-6-methylpyridin-2(1H)-one
