Reaction Conditions

Reaction Steps

A mixture of 2,6-dibromo-4-fluoro-phenylamine (1.00 g, 3.72 mmol), benzoyl isothiocyanate (0.600 ml, 4.46 mmol), dimethyl-pyridin-4-yl-amine (45.0 g, 0.370 mmol), and toluene (5 ml) was stirred at 23° C. for 16 hours. The resulting precipitate was collected by filtration and washed with hexane to yield titled compound (1.37 g, 85%). MS (ESI/CI): mass calcd. for C14H9Br2FN2OS, 429.9; m/z found, 430.9 [M+H]+. 1H NMR (400 MHz, CD3OD-d4): 8.05-7.98 (m, 2H), 7.73-7.66 (m, 1H), 7.62-7.55 (m, 4H).
