Stage #1: With borane-THF In tetrahydrofuran for 3 h; Heating / reflux
Stage #2: With water; sodium carbonate In tetrahydrofuranHeating / reflux
BH3. DMS (1.0 mL, 10.66 mmol) was refluxed in THF (20 mL) for 30 min (formation of BH3. THF). At RT, Example 17 (2.0 g, 10.66 mmol in 10 mL THF) was added dropwise, and then the reaction mixture was heated to reflux for 3 h. The solution was allowed to cool to ambient temperature, solid sodium carbonate (0.5 g) and water (5 mL). The resulting mixture was heated for a short while and poored in water (50 mL). Extraction with ethyl acetate (3 x 50 mL), drying of the combined organic layers (Na2SO4) and evaporation in vacuo gave a 1: 1 mixture of starting material and product. Purification by flash column chromatography over silica gel eluting with ethyl acetate gave 780 mg (42 percent) of an off-white solid.

2 g With borane-THF In tetrahydrofuran at 0 - 20℃; for 20.5 h; Inert atmosphere To a solution of 2-chloro-6-methoxyisonicotinic acid (2.5 g) in dry tetrahydrofuran (50 ml) at 0°C under nitrogen was added dropwise a solution of borane- tetrahydrofuran complex (1.0M solution in tetrahydrofuran; 40 ml) over fifteen minutes. After the addition was complete, the cooling bath was removed and the mixture allowed to warm to room temperature. After three hours, the mixture was cooled to 0°C and borane-tetrahydrofuran complex (1.0M solution in tetrahydrofuran; 40 ml) was addedover fifteen minutes. After the addition was complete, the cooling bath was removed and the mixture allowed to warm to room temperature and stirred for seventeen hours. The reaction mixture was cooled to 0°C, quenched with 1.0M aqueous sodium hydroxide solution (30 ml), diluted with saturated aqueous ammonium chloride solution (50 ml) and extracted with diethyl ether (2 x 100 ml), the combined organic layer washed with brine then dried (Na2SC"4) and evaporated. The residue was triturated with hexane and filtered to afford (2-chloro-6-methoxypyridin-4-yl)methanol (2.0 g) as a white solid.
