YieldReaction ConditionsOperation in experiment
78.7% With methanol; sodium tetrahydroborate; at 0 - 20℃; for 1h; Example 1 1-(5-(4-Chloro-2-fluorobenzyloxy)pyridin-2-yl)-2-(2,4-difluorophenyl)-1,1-difluoro-3-(1H-tetrazol-1-yl)propan-2-ol (1)1-(Bromomethyl)-4-chloro-2-fluorobenzene was prepared using the following two-step procedure. To a stirred solution of 4-chloro-2-fluorobenzaldehyde (1.0 g, 6.31 mmol) in methyl alcohol (CH3OH; 15 mL) was added sodium borohydride (NaBH4; 0.47 g, 12.6 mmol) at 0 C. The reaction mixture was stirred at RT for 1 h. After consumption of the starting material (by TLC), the reaction mixture was quenched with ice pieces, and the volatiles were evaporated under reduced pressure. The residue was diluted with H2O (25 mL) and extracted with EtOAc (2×50 mL). The combined organic layers were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The obtained crude material was purified by column chromatography (SiO2, 100-200 mesh) to afford the corresponding alcohol (0.8 g, 5.0 mmol, 78.7%) as a semi solid. 1H NMR (200 MHz, CDCl3): delta 7.41 (q, J=8.0, 15.6 Hz, 1H), 7.17-7.05 (m, 2H), 4.73 (d, J=6.2 Hz, 2H), 1.83 (t, J=6.2 Hz, 1H).
With hydrogenchloride; sodium borohydrid; In 1,4-dioxane; methanol; (1) First, 25 g of 4-chloro-2-fluorobenzaldehyde was dissolved in a mixed solvent consisting of 250 ml of 1,4-dioxane and 25 ml of methanol, to which 2.4 g of sodium borohydride was added under ice cooling, and the mixture was stirred for 30 minutes. After completion of the reaction, a small amount of diluted aqueous hydrochloric acid was added, and the reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried, and concentrated. The residue was subjected to silica gel column chromatography, which afforded 25 g of 4-chloro-2-fluorobenzyl alcohol. 1 H--NMR (300 MHz, CDCl3): delta (ppm) 1.82 (1 H, t, J=6.1 Hz), 4.72 (2 H, d, J=6.1 Hz), 7.08 (1 H, dd, J=2.1, 9.8 Hz), 7.15 (1 H, dd, J=2.1, 8.2 Hz), 7.37 (1 H, dd, J=8.2, 8.2 Hz)
With sodium tetrahydroborate; In methanol; at 0 - 20℃; for 1.5h; 4.75 g of 4-chloro-2-fluorobanzaldehyde and 30 ml of methanol were mixed. It was cooled to 0 C, and 0.57 g of sodium borohydride was added to it, and stirred at 0 C for 30 minutes and at room temperature for 1 hour. Water was added to the reaction mixture, and concentrated under reduced pressure. The obtained residue was extracted with chloroform. The organic layer was washed successively with 5 % hydrochloric acid, saturated aqueous solution of sodium chloride, dried by magnesium salfate, and concentrated under reduced pressure to obtain 4.57 g of (4-chloro-2-fluorophenyl)methanol.1H-NMR (CDCl3, TMS) delta (ppm): 7.37 (1H, t, J=8.0 Hz), 7.12-7.17 (1H, m), 7.08 (1H, dd, J=9.7 Hz, 1.9 Hz), 4.73 (2H, s), 2.04 (1H, br.s)
