Versuchsvorschrift
To a stirred mixture of 0.35 g (2.0 mmol) of (N-methyl)isoquinoline-1,3(2H,4H)-dione, 3.2 ml of Ac2O, and 0.80 ml of N,N-DIMETHYLFORMAMIDE (DMF) is added 0.44 ml (4.0 mmol) of (MeO)3CH at 25° C. The mixture is stirred at 125° C. for 30 m, cooled, and concentrated under high vacuum. The residue is recrystallized from Et2O-hexane to give 0.20 g of tan solid, mp 145-150° C. (dec); MS (ES+) m/z 218.2 (M+H)+1.
