Reaction Steps
Concentrated aqueous ammonium hydroxide (10 mL) was added to a solution of 4-chloro-5-iodo-2-(trifluoromethyl)pyridine (4.11 g, 13.3 mmol) in DMSO in a glass pressure tube. The tube was sealed and placed in an oil bath pre-heated to 110° C. for 48 h. The resulting solution was diluted with brine, extracted with ethyl acetate, dried (Na2SO4), filtered and concentrated under vacuum to give 5-iodo-2-(trifluoromethyl)pyridin-4-amine. Retention time (min)=1.584, method [1], MS (ESI) 289.0 (M+H).
