Yield	Reaction Conditions	Operation in experiment
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).

The resulting reaction mixture was degassed with nitrogen for 5 minutes then copper (I) iodide (0.59 g, 3.12 mmol) was added, followed by transN,N'dimethylcyclohexane1,2diamine (2.59 mL, 16.4 mmol). The resulting mixture was degassed again for 10 minutes and heated at 110 °C for 1 h under microwave irradiation. The reaction mixture was cooled to ambient temperature, filtered through Celite® and the organic layer was concentrated under reduced pressure. The residue was purified by column chromatography (Redisep24 g, 2040percent EtOAc/ nhexane) to obtain Intermediate 6 (1.15 g, 52.10percent) as pale yellow solid. 1H NMR (300 MHz, DMSOd6) G^ppm 2.62 (s, 3 H), 8.10 (s, 1 H), 8.38 (s, 1 H), 8.95 (s, 1 H), 9.37 (s, 1 H), 9.98 (s, 1 H).
