Procedure
N-Cyclopropyl-3-(7-hydroxy-1-oxoisoquinolin-2(1H)-yl)-4-methylbenzamide (250 mg), N-phenyltrifluoromethanesulfonamide (267 mg) and potassium carbonate (311 mg) were stirred in THF (6 ml) and heated under microwave irradiation (Personal Chemistry Emrys Optimizer with 300 W magnetron) at 120° C. for 10 minutes. The reaction mixture was diluted with ethyl acetate and washed with water (2×), brine, dried (magnesium sulfate) and concentrated. Purification by column chromatography with a gradient of iso-hexane to 70% ethyl acetate/iso-hexane yielded 2-{5-[(cyclopropylamino)carbonyl]-2-methylphenyl}-1-oxo-1,2-dihydroisoquinolin-7-yl trifluoromethanesulfonate as a cream coloured solid (264 mg); NMR Spectrum: (DMSOd6) 0.53 (m, 2H), 0.67 (m, 2H), 2.10 (s, 3H), 2.83 (m, 1H), 6.87 (d, 1H), 7.49 (m, 2H), 7.76 (s, 1H), 7.86 (d, 1H), 7.93 (d, 1H), 8.00 (d, 1H), 8.19 (s, 1H), 8.42 (d, 1H); Mass Spectrum: M+Na+ 489.
