실험 절차

To a solution of 3,5-dichloropyridin-4-amine (4.0 g, 24.53 mmol) in DCM (20 mL), was added N-ethyl di-isopropyl amine (6.3 g, 48.83 mmol). The reaction mixture was stirred at RT for 30 minutes. The reaction mixture was cooled at 0° C. and thiophosgene (2.76 g, 24.00 mmol) was added drop wise. The reaction mixture was stirred at 0° C. to RT for 3-4 h. The reaction mixture was diluted with DCM and the obtained crude was purified by column chromatography to afford 1.0 g of the desired product. 1HNMR (DMSO-d6): δ 8.77 (s, 2H); MS [M+H]+: 205.20.
