Versuchsvorschrift

(R)-2-(1-hydroxypropan-2-yl)-5-nitroisoquinolin-1(2H)-one (19 g, 0.073 mol), acetic anhydride (10 g, 0.1 mol), triethylamine (30 g, 0.3 mol), 4,4-dimethylaminopyridine (200 mg, 0.002 mol) and methylene chloride (500 mL, 8 mol) were stirred at room temperature overnight. The solvents were removed under reduced pressure and the residue was purified flash chromatography to afford the title compound as a yellow oil (21 g, 100% yield).
