(3,5-二溴-4-氯苯基)甲醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: (3,5-Dibromo-4-chlorophenyl)methanol: NaBH4 (1.53 g, 40.65 mmol) was added portionwise to a stirred solution of methyl 3,5-dibromo-4-chlorobenzoate (4.45 g, 13.6 mmol) in MeOH (50 mL) at 0° C. The reaction mixture was then stirred at ambient temperature for 8 h. The volatiles were evaporated and the residue was diluted with CH2Cl2 and washed with brine followed by water. The organic layer was dried (Na2SO4), filtered and concentrated to afford the title compound as an off white solid (3.3 g, 80%): 1H NMR (300 MHz, DMSO-d6) δ 7.71 (s, 2H), 5.49 (bs, 1H), 4.48 (d, J=4.5 Hz, 2H); ESIMS m/z 297.9 ([M]+); IR (thin film) 3460, 747, 534 cm−1. The volatiles were evaporated the residue was diluted with CH2Cl2 washed with brine The organic layer was dried (Na2SO4) filtered concentrated

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Pyridinium chlorochormate (PCC, 3.44 g, 15.9 mmol) was added in one portion to a stirred solution of (3,5-dibromo-4-chlorophenyl)methanol (3.2 g, 11.0 mmol) in CHCl3 (40 mL) at ambient temperature and the reaction mixture was stirred overnight. The reaction mixture was filtered through Celite®, the Celite® pad was washed with CHCl3 and the filtrate was concentrated to afford the title compound as an off white solid (2.0 g, 62%): mp 110-113° C.; 1H NMR (300 MHz, DMSO-d6) δ 9.93 (s, 1H), 8.27 (s, 2H); ESIMS m/z 297.0 ([M]+). The reaction mixture was filtered through Celite® the Celite® pad was washed with CHCl3 the filtrate was concentrated
