94.47% | With sodium tetrahydroborate; In methanol; at 80℃; for 0.5h; | NaBH4 (128.38 mg, 3.39 mmol) was added to a solution of 150.00 g Compound BD1- 1 (i.e., <strong>[357405-75-5]4-bromo-2,5-difluorobenzaldehyde</strong>) in MeOH (4.00 mL). The mixture was stirred at 80C for 30 minutes. TLC indicated Compound BDl-l was consumed completely in this reaction time. An additional compound with a larger polarity than Compound BDl-l was measured. The reaction mixture was concentrated to remove MeOH, then diluted with saturated NaHC03 (4 ml), extracted with DCM (5 mL * 3), the combined organic layer was washed with saturated brine (5 mL * 2), dried over Na2S04, filtered and concentrated to give a residue. The residue was purified by prep-TLC (S1O2, Petroleum ether:Ethyl acetate mixture with a ratio of 3: 1) to afford Compound BDl-2 (143.00 mg, 641.23 tauetaomicron, 94.47% yield) as a white solid. |
