2-(3-溴苯基)-2,2-二氟乙醇

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

实验步骤: Obtained from Intermediate 49 (17.6 g, 74 mmol) by the procedure described in Intermediate 3. The crude oil was purified by distillation to yield the title compound as oil of 60% of purity (9.5 g). The distillation residue was purified by column chromatography with silica gel and methylene chloride as eluent to yield a second batch of 1-bromo-3-{2-[(6-bromohexyl)oxy]-1,1-difluoroethyl}benzene of 65% of purity (15.2 g) (overall yield: 53%). The crude oil was purified by distillation

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

实验步骤: Obtained from Intermediate 48 (21.1 g, 75.8 mmol) by the procedure described in Intermediate 2. The title compound was obtained (17.2 g, 96%) as oil.
