Reaction Steps

7-(5-Fluoro-2-methylphenyl)isoquinolin-3-amine (150 mg, 0.595 mmol), 2,2-difluoroacetic acid (171 mg, 1.78 mmol), 4-(Dimethylamino)pyridine (18 mg, 0.15 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (676 mg, 1.78 mmol) were dissolved in pyridine (20 mL). After the reaction mixture was stirred at room temperature overnight, water (1 mL) was added and it was extracted with ethyl acetate. It was concentrated and purified by prep-HPLC to give the desired product (59.6 mg). LCMS (ESI): RT (min)=1.161, M+H+=330.9, method=A; 1H NMR (400 MHz, DMSO-d6) δ 11.48 (s, 1H), 9.22 (s, 1H), 8.50 (s, 1H), 8.08 (s, 1H), 8.03 (d, J=8.4 Hz, 1H), 7.75 (d, J=8.4 Hz, 1H), 7.38-7.34 (m, 1H), 7.16 (d, J=8.8 Hz, 2H), 6.44 (t, J=54.0 Hz, 1H), 2.22 (s, 3H).
