Reaction Steps

To an ice cold solution of 4-(6-aminopyridin-3-yl)tetrahydro-2H-thiopyran 1,1-dioxide (140 mg, 0.62 mmol) in DCM (15 mL) was added NBS (110 mg, 0.62 mmol) in two portions. The reaction mixture was stirred at 0° C. for 20 min. The reaction solution was diluted with ethyl acetate, washed with water, saturated aqueous sodium bicarbonate solution, brine, dried over sodium sulfate and concentrated to give 4-(6-amino-5-bromopyridin-3-yl)tetrahydro-2H-thiopyran 1,1-dioxide (190 mg, 0.62 mmol). LCMS (m/z): 305/307 (MH+), 0.33 min.
