To a solution of 7-bromo-2,3,4,5-tetrahydro-1H-pyrido[2,3-e][1,4]diazepine (432 mg, 1.89 mmol) and TEA (0.28 mL, 2.02 mmol) in anhydrous CH2Cl2 (20 mL) under argon was added methanesulfonyl chloride (0.16 mL, 2.06 mmol). The mixture was stirred for 12 h at room temperature. Mixture was then concentrated to a brown solid and redissolved in a 2:1 MeOH:DMSO mixture. Purification by preparative HPLC (water/acetonitrile/0.05% TFA mixture) gave the title compound (7-bromo-4-(methylsulfonyl)-2,3,4,5-tetrahydro-1H-pyrido[2,3-e][1,4]diazepine) (281 mg, 48%) as a yellow solid: 1H NMR (200 MHz, DMSO-d6) δ 8.02 (s, 1H), 7.68 (s, 1H), 4.39 (s, 2H), 3.48 (s, 2H), 3.39 (s, 2H), 2.79 (s, 3H).
