99% With sodium tetrahydroborate In tetrahydrofuran; methanol at 0 - 20℃; for 4 h; (3-Bromopyridin-2-yl)methanol (B5.2) (0363) To a mixture of B5.1 (1 g, 5.4 mmol) in MeOH (20 mL) and THF (10 mL) was cooled to 0° C., NaBH4 (0.82 g, 21.6 mmol) was added in portions. The mixture was stirred for 4 h at rt. The mixture was concentrated, diluted with water (40 mL), extracted with DCM (40 mL×3), the organic layer was washed with brine, dried over Na2SO4, filtered and concentrated to give the title compound (1 g, 99percent) as a white solid. LC-MS: [M+H]+=190.0.

YieldReaction ConditionsOperation in experiment
92% at 0 - 20℃; N-((4-chloro-2-methylphenyl)(phenyl)methyl)-2-(2-(2-(hydroxymethyl)pyridin-3-yl)benzofuran-5- yl)acetamidea) (3-bromopyridin-2-yl)methanolTo a solution of methyl 3-bromopicolinate (1 g, 4.6 mmol) in MeOH (50 mL) at 0 °C was added NaBH4 (883 mg, 23.2 mmol). The reaction mixture was stirred at rt overnight, followed by concentration under reduced pressure. The resultant residue was dissolved in EtOAc (50 mL), washed with aq. NH4C1 (3 x 20 mL), dried over Na2S04, filtered, and concentrated to afford the title compound (101 g, 92percent) as a white solid. LCMS-P 1 : 190/192 [M+H]+; Rt: 1.070 min
82% at 0 - 20℃; for 24 h; To a solution of Example 46a (2 g, 9.2 mmol) in methanol (100 mL) was added NaBH4 (1.8 g, 46.4 mmol) portionwise at 0°C and slowly warmed to r.t. for 24hrs. After the reaction was completed, the solvent was removed under reduced pressure, and the residue was dissolved in EtOAc (50 mL), washed with aq. NH4C1 (20 mL*3), dried over Na2S04, filtered and concentrated to afford the desired product (Example 58a, 1.4 g, yield 82percent) as a white solid. LCMS [M+1]+=188
62% at 0 - 20℃; Intermediate 5 (3-Bromo-pyridin-2-yl)-methanol 3-Bromo-pyridine-2-carboxylic acid methyl ester (12.8 g, 59 2 mmol) is dissolved in methanol (150 mL) and cooled to 0° C. To the mixture is added NaBH4 (11.2 g, 296 mmol) in 1.0 g portions. The mixture is warmed to room temperature and stirred for 3 h. The methanol is removed under reduced pressure, ethyl acetate is added and the solution is washed with saturated, aqueous ammonium chloride and brine. The organic portion is dried over MgSO4, filtered, and concentrated under reduced pressure to yield 6.8 g (62percent) of the title compound as a white solid. GCMS m/e 187, 189 [M]-
