実験手順

To a solution of N-(3-amino-4-methylphenyl)-3-(2-cyanopropan-2-yl)benzamide 5 (2.56 mmol, 750 mg) and triethylamine (12.78 mmol, 1.782 mL) in CH2Cl21 ml at 0° C. was added 3-chlorothieno[2,3-b]pyrazine-6-carbonyl chloride 94 in 1 mL CH2Cl2 and stirred at rt for 1 h. The reaction mixture was quenched with water, extracted with CH2Cl2 (2×). The organic layer was dried and concentrated under reduced pressure. Purified with column chromatography (10-20% ethyl acetate in CH2Cl2) gave 3-chloro-N-(5-(3-(2-cyanopropan-2-yl)benzamido)-2-methylphenyl)thieno[2,3-b]pyrazine-6-carboxamide 95 (1.04 g, 83%). NMR (400 MHz, DMSO-d6) 1.76 (s, 6H), 2.26 (s, 3H), 7.32 (d, J=8.2 Hz, 1H), 7.59 (d, J=7.8 Hz, 1H), 7.64 (dd, J=8.2 Hz and 2.0 Hz, 1H), 7.76 (d, J=7.8 Hz, 1H), 7.87 (d, J=2.3 Hz, 1H), 7.95 (d, J=7.8 Hz, 1H), 8.05 (s, 1H), 8.57 (s, 1H), 8.98 (s, 1H), 10.37 (s, 1H), 10.56 (s, 1H).
