38% | at 110℃; for 5 h; | Intermediate 6; 2-chloro-4-(trifluoromethyl)nicotinonitrile; A mixture of 4-(trifluoromethyl)nicotinonitrile 1-oxide (10.5 g, 55.8 mmol) and POCl3 (51 mL, 558 mmol) was heated at 110 °C for 5 hours. After evaporation of excess POCl3, the residue was taken up in dichloromethane and washed successively with 5percent K2CO3 and water. The organic phase was then dried over Na2SO4, filtered and concentrated to give a mixture of the title compound and 6-chloro-4-(trifluoromethyl)nicotinonitrile. 1H NMR analysis of the crude material showed that the title compound was the major isomer (7:3 2- EPO <DP n="38"/>chloro:6-chloro). The isomers were separated by flash chromatography. The 6-chloro isomer was eluted first with 9:1 hexanes:Et3N. Eluting with dichloromethane gave the title compound as an orange oil (4.50 g, 38percent). |
