Reaction Steps

To a suspension of 4-bromoquinoline-8-carbonitrile (100 mg, 0.43 mmol) in 4 mL of iso-propanol, 3-(trifluoromethyl)benzylamine (150 mg, 0.85 mmol, 2.0 equiv.) and K2CO3 (119 mg, 0.85 mmol, 2.0 equiv.) were added. The resulting mixture was stirred at 110° C. 2 days. After work-up, the crude was purified by preparative HPLC to yield the title compound as TFA salt in 20% yield. 1HNMR (in MeOD): 4.96 (s, 2H), 6.96 (d, J=7.0 Hz, 1H), 7.58-7.71 (m, 3H), 7.76 (s, 1H), 7.86 (dd, J=7.7 and 8.8 Hz, 1H), 8.39 (d, J=7.3 Hz, 1H), 8.44 (dd, J=1.1 and 7.3 Hz, 1H), 8.75 (dd, J=1.1 and 8.8 Hz, 1H). Mass: M+H+: 328.
