Reaction Steps
Dissolve 3-(hydroxymethyl)-3,4-dihydro-2H-isoquinolin-1-one (6.0 g, 33.86 mmol) in DCM (60 mL) and add triethylamine (7.25 g, 67.72 mmol). Cool to 0° C. and add methanesulfonyl chloride (4.65 g, 40.63 mmol) drop-wise. Stir for one hour; dilute with DCM; and wash with water and then brine. Remove the solvents under reduced pressure to give the title compound (8.0 g, 92%). MS (m/z): 256 (M+1).
