(4-甲氧基苯基)甲基 甲磺酸盐

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

实验步骤: Prepare by the method of Example 17.3 using 4-methoxybenzyl mesylate and 1-(3,4,5-trimethoxybenzyl)-3-(2-(t-butyldimethylsilyloxy)ethyl)-2-oxopyrrolidine to give the title compound: Rf=0.15 (silica gel, 1/4 ethyl acetate/hexane).

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

实验步骤: Combine 4-methoxybenzyl alcohol (45.4 mmol), N,N-diisopropylethylamine (12.9 g, 100 mmol), and acetonitrile (60 mL). Cool in an ice bath. Add methanesulfonyl chloride (6.76 , 49.0 mmol). After 2 hours, partition the reaction mixture between water and ethyl acetate. Separate the layers and extract the organic layer with 1 M hydrochloric acid solution and then a saturated solution of sodium bicarbonate. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give the title compound. Cool in an ice bath partition the reaction mixture between water and ethyl acetate Separate the layers extract the organic layer with 1 M hydrochloric acid solution Dry the organic layer over Na2SO4 filter evaporate in vacuo
