Reaction Steps

Scheme O was used for the preparation of 5-fluoro-8-methylisoquinolin-3-amine from 12.0 g of 5-ethoxy-4-(ethoxymethyl)-1-[3-fluoro-5-(trifluoromethyl)phenyl]pentane-2,3-diimine start material to give 5.9 g, yield 69.4%. 1H NMR (400 MHz, DMSO-d6) ppm 6.39 (s, 2H), 6.77 (d, J=1.01 Hz, 1H), 7.91 (dd, J 9.06, 2.52 Hz, 1H), 7.97 (dd, J=8.81, 2.27 Hz, 1H), 8.94 (s, 1H).
