邻甲苯海明EP杂质A

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

实验步骤: A solution of 15 (1.44 g, 5 mmol, 1.0 equiv) and o-anisidine (16) (0.62 g, 0.56 mL, 5 mmol, 1.0 equiv) in toluene (15 mL) was refluxed overnight with H2O removal (Dean-Stark trap). The mixture was cooled to room temperature and concentrated under reduced pressure to give crude 5 as a yellow oil that was used without purification. concentrated under reduced pressure

实验步骤: To a solution of 28.1 g (140 mmol) of 5 in 150 mL of dry diethyl ether, 25.6 g (8.89 mL, 94.4 mmol) of PBr3 was added at −10° C. The resulting mixture was stirred for 12 hr at room temperature and then added to 450 mL of cold water. The organic layer was separated, and the aqueous layer was extracted with 2×150 mL of water. The combined organic extracts were washed with aqueous NaHCO3, dried over Na2SO4, and then evaporated to dryness. This procedure gave 33.0 g (89%) of the title product. The organic layer was separated the aqueous layer was extracted with 2×150 mL of water The combined organic extracts were washed with aqueous NaHCO3 dried over Na2SO4 evaporated to dryness
