Reaktionsschritte

To a cooled (ice-water) solution of the product of step 1 (800 mg, 1.87 mmol) and DIPEA (0.675 mL, 3.75 mmol) in DCM (10 mL) is slowly added methanesulfonyl chloride (0.150 mL, 1.87 mmol). The reaction mixture is stirred at room temperature for 6 hours. The reaction is diluted with DCM (10 mL), washed with water (2×10 mL) dried over Na2SO4 and concentrated under reduced pressure to give the title compound (813 mg): LCMS m/z (Cl): 445 [M+H].
