Diethyl Ether → Isoquinoline, 4-bromo-7-chloro-, 2-oxide

Participants

Reaction Steps

4-bromo-7-chloroisoquinoline (3-6)(1 g, 4.12 mmol, 1.0 equiv.) was dissolved in anhydrous CH2Cl2 (8.2 mL) and treated with mCPBA (1.622 g, 9.40 mmol, 2.3 equiv.). The reaction mixture was stirred at room temperature, forming 3-7 as a white precipitate. Following dilution with Et2O, the solid was collected and used without further purification in the next step. LRMS m/z (M+H) 260.1 found, 259.9 required.
