Reaction Steps

To a cooled (ice-water) solution of (6-bromothiazolo[5,4-b]pyridin-2-yl)methanamine (800 mg, 3.28 mmol) and pyridine (800 mg, 9.85 mmol) in CH2Cl2 (10 mL) is slowly added methanesulfonyl chloride (380 mg, 3.28) and stirred at room temperature for 3 hours. Reaction mixture is washed with water (2×10 mL) dried over Na2SO4 and concentrated. Obtained crude product purified on silica gel column using 0 to 5% methanol/CH2Cl2 to give the title compound (800 mg): m/z (Cl) M+2 324.
