実験手順: To a solution of (5,6-dichloropyridin-3-yl)methanol (275 mg, 1.55 mmol) in DMSO (5 mL) were added tert-butyl 2,4,5-trifluorobenzoate (Preparation 97, 300 mg, 1.30 mmol), and potassium carbonate (535 mg, 3.88 mmol) and the mixture stirred for 18 hours at room temperature under a nitrogen atmosphere. Water (10 mL) was added and the mixture extracted with EtOAc (3×20 mL). The combined organics were washed with water (20 mL) and concentrated in vacuo to yield the title compound (490 mg, 96%). the mixture extracted with EtOAc (3×20 mL) The combined organics were washed with water (20 mL) concentrated in vacuo

実験手順: A mixture of 5-chloro-6-methoxypyridin-3-ol (Preparation 77, 100 mg, 0.627 mmol), tert-butyl 2,4,5-trifluorobenzoate (Preparation 6, 147 mg, 0.633 mmol), and potassium carbonate (260 mg, 1.88 mmol) in DMSO (5 ml) was stirred overnight at 25° C. under a nitrogen atmosphere. The reaction was diluted with water (50 mL) and extracted with EtOAc (3×30 mL). The combined organics were washed with aqueous sodium hydroxide solution (1.0 M, 30 mL), brine (2×40 mL), dried over sodium sulfate, filtered and concentrated in vacuo. The crude was purified by silica gel chromatography eluting with 5% EtOAc in heptane to afford the title compound as a white solid (65 mg, 28%): extracted with EtOAc (3×30 mL) The combined organics were washed with aqueous sodium hydroxide solution (1.0 M, 30 mL), brine (2×40 mL) dried over sodium sulfate filtered concentrated in vacuo The crude was purified by silica gel chromatography eluting with 5% EtOAc in heptane

実験手順: tert-Butyl 2,4,5-trifluorobenzoate (Preparation 6, 0.200 g, 0.86 mmol), 5-chloro-6-[(3,3-difluorocyclobutyl)methoxy]pyridin-3-ol (Preparation 5, 0.258 g, 1.03 mmol) and potassium carbonate (0.178 g, 1.29 mmol) were suspended in DMSO (5.0 mL). The mixture was stirred at room temperature under nitrogen for 16 hours. EtOAc (50 mL) was added and the mixture was washed with water (3×150 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to afford the title compound (0.400 g, 101%): the mixture was washed with water (3×150 mL) The organic layer was dried over sodium sulfate filtered concentrated in vacuo

実験手順: Potassium carbonate (535 mg, 3.88 mmol) was added to a solution of tert-butyl 2,4,5-trifluorobenzoate (Preparation 10, 275 mg, 1.29 mmol) and (5,6-dichloropyridin-3-yl)methanol (241 mg, 1.36 mmol) in DMSO (5 mL). The reaction mixture was stirred at RT for 18 hours. After cooling the reaction mixture was quenched with water (25 mL) and extracted with ethyl acetate (2×50 mL). The combined organic layers were washed with water (2×100 mL) and dried over MgSO4, filtered and concentrated in vacuo to give 490 mg of the title compound in a quantitative yield. The crude compound was used without further purification.
