Reaction Steps

2-[3-Bromo-2-(tert-butyl-dimethyl-silanyloxymethyl)-phenyl]-3-hydroxy-7-(1-methyl-cyclopropyl)-3,4-dihydro-2H-isoquinolin-1-one (1.134 g, 2.2 mmol) was dissolved in 13 ml dichloromethane at room temperature; triethylamine (1.31 ml, 9.44 mmol) followed by addition of methanesulfonyl chloride (0.478 g, 4.171 mmol) were added. It was stirred for 1.5 hours at room temperature but it's already done in 10 minutes according to LCMS. The reaction mixture was extracted with dichloromethane/water; organic phase was washed with brine; dried over sodium sulfate; filtered; concentrated to give 2-[3-Bromo-2-(tert-butyl-dimethyl-silanyloxymethyl)-phenyl]-7-(1-methyl-cyclopropyl)-2H-isoquinolin-1-one (1.094 g, 2.2 mmol) MS (ESI) 520.0 (M+Na+).
