Participants

Reaction Steps

4-Chloro-2-fluoro-5-(2-pyrimidinyloxy)-benzenamine (50 g) and triethyl amine (42.2 g) were dissolved in anhydrous ethyl acetate (400 ml) and stirred under ice cooling. Thiophosgene (74.3 g) dissolved in ethyl acetate (400 ml) was slowly added to the stirred solution. The mixture was heated at reflux for 2 hr and filtered. Evaporation of the solvent afforded 2-(2-chloro-4-fluoro-5-isothiocyanatophenoxy)-pyrimidine which was used for the next step without purification. 1H NMR, CDCl3, 7.12 (1H, t, J=4.7 Hz), 7.13 (1H, d, J=7.0 Hz), 7.32 (1H, d, J=8.9 Hz), 8.58 (2H, t, J=4.7 Hz).
