실험 절차

A mixture of 4-(5-amino-6-(hydrazinecarbonyl)pyrazin-2-yl)-N,N-dimethylbenzamide (75 mg, 0.2497 mmol), isothiocyanatomethylbenzene (37.26 mg, 33.12 μL, 0.2497 mmol) and dry THF (1.500 mL) was stirred at RT for 4 hours. The reaction mixture was evaporated to dryness and treated with DCM followed by EDC (71.81 mg, 0.3746 mmol) and the resultant mixture allowed to stir at RT overnight. The reaction mixture was filtered and the resultant green precipitate dried under vacuum (78 mg, 73% Yield). 1H NMR (400.0 MHz, DMSO) d 2.96 (s, 3H), 3.00 (s, 3H), 4.50 (d, J=6.1 Hz, 2H), 7.29 (d, J=7.2 Hz, 1H), 7.35-7.42 (m, 4H), 7.51-7.53 (m, 2H), 7.65 (br s, 2H), 8.06 (dd, J=1.5, 6.9 Hz, 2H) and 8.81 (d, J=12.4 Hz, 2H) ppm; MS (ES+) 416.2
