Reaction Steps

A solution of 6-bromo-3-methyl-pteridin-4-one (5.516 g, 22.88 mmol) in 2-methoxyethanol (50.81 mL) was treated with 1-ethylsulfonylpiperazine (6.118 g, 34.32 mmol) and the resulting suspension heated for 2 hours at 100° C. The reaction mixture was cooled in an ice-water bath and resultant precipitate collected and washed with cold methanol to give the product as a yellow solid (5.02 g, 65% Yield). 1H NMR (400.0 MHz, DMSO) d 1.25 (t, 3H), 3.10 (q, 2H), 3.34 (m, 4H), 3.49 (s, 3H), 3.85 (m, 4H), 8.37 (s, 1H), 8.84 (s, 1H) ppm; MS (ES+) 339
