A solution of 6-(bromomethyl)thieno[3,2-b]pyrazine 47 (50 mg, 0.218 mmol), N-(3-amino-4-methylphenyl)-3-(2-cyanopropan-2-yl)benzamide hydrochloride 6 (72 mg, 0.218 mmol) and potassium carbonate (90 mg, 0.655 mmol) in acetonitrile (2 mL) was stirred overnight at 50° C. Water was added and extracted with EtOAc. Organic layer was washed with brine, dried and evaporated. Purification by HPLC gave the title compound 3-(2-cyanopropan-2-yl)-N-(4-methyl-3-(thieno[2,3-b]pyrazin-6-ylmethylamino)phenyl)benzamide 48 (6 mg, 6.23%). NMR (400 MHz, DMSO-d6) 1.71 (s, 6H), 2.16 (s, 3H), 4.72 (d, J=5.5 Hz, 2H), 6.02 (t, J=6.2 Hz, 1H), 6.98 (s, 2H), 7.08 (s, 1H), 7.54 (m, 2H), 7.70 (d, J=7.8 Hz, 1H), 7.83 (d, J=7.8 Hz, 1H), 7.92 (t, J=1.6 Hz, 1H), 8.50 (d, J=2.3 Hz, 1H), 8.66 (d, J=2.3 Hz, 1H), 10.00 (s, 1H).
