Procedure
1-{5-({[tert-Butyl(diphenyl)silyl]oxy}methyl)-4-[(2R,6S)-2,6-dimethylmorpholin-4-yl]-2,3-difluorophenyl}-1-(5-chloropyrazin-2-yl)-N-hydroxymethanimine (Intermediate 200, 400 mg, 0.61 mmol) in DMF (5 mL) was treated with sodium thiomethoxide (45.3 mg, 0.61 mmol) at room temperature, the mixture was stirred at room temperature for 10 min. K2CO3 (5 eq) was added and the mixture was heated to 100° C. for 1 hour. The reaction mixture was diluted with ethylacetate (20 ml). Organic layer washed with water and brine, then dried over sodium sulfate, filtered, and the filtrate was concentrated, purified by silica gel column chromatography (Hexanses/EtOAc, gradiant) to give the desired product (97 mg, 39.0%).
