1-(4-氯苯基)-1-苯基乙醇

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

实验步骤: To 37 ml of a 2M solution of phenylmagnesium bromide in tetrahydrofuran was added, under argon atmosphere, 5.24 g (33.9 mmol) of p-chloroacetophenone, and the mixture was allowed to react at 0° C. for 3 hours. At the completion of this reaction, a saturated aqueous solution of ammonium chloride was added to the reaction mixture, which was then extracted with chloroform. The organic layer was washed with water and then concentrated by evaporation under reduced pressure. The residue was subjected to silica gel column chromatography, eluted with chloroform, to give 6.99 g (30.0 mmol) of 1-phenyl-1-(p-chlorophenyl)ethanol. To a solution of 6.99 g (30.0 mmol) of the alcohol compound in ethanol (80 ml) was added 5.00 ml (93.8 mmol) of conc. sulfuric acid, and the mixture was reacted for 1 hour. to react at 0° C. for 3 hours At the completion of this reaction was then extracted with chloroform The organic layer was washed with water concentrated by evaporation under reduced pressure eluted with chloroform

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

实验步骤: Following a procedure similar to that described in Preparation 8(a), but using 1-(4-chlorophenyl)-1-phenylethanol and 1-(2-chloroethyl)-4-(ethoxycarbonyl)piperazine, the title compound was obtained in a yield of 89%.
