Procedure

A mixture of 2-(2-(2-tert-butylphenoxy)pyridin-3-ylamino)-4-(trifluoromethyl)thiazole-5-carbonitrile (Example 404, 177 mg, 0.42 mmol), hydroxylamine hydrochloride salt (145 mg, 2.1 mmol), DIPEA (732 μL, 4.2 mmol) in ethanol (5 mL) was heated at 60° C. for 5 h. The reaction was diluted with ethyl acetate and washed with brine. The organic layer was separated and evaporated to give the crude product. Purification of the crude product by flash chromatography (silica, 0-80% EtOAc/hexane gradient) gave Example A53a (120 mg) as white crystals. (M+H)+=452.1.
