Sodium hydride → 1-((4-Methoxybenzyloxy)methyl)-4-bromobenzene

참여 물질

반응 단계

A solution of 4-bromobenzyl alcohol (2.011 g, 10.7 mmol) in THF (42 mL) was added to a mixture of NaH (663 mg, 16.6 mmol, 60% in oil) in DMF (13 mL). The mixture was stirred for 1.5 h and 4-methoxybenzyl chloride (MPMCl, 2 mL, 14.8 mmol) was added. After 24 h, 100 mL saturated NH4Cl solution was added. The resulting mixture was extracted with ethyl acetate (3×60 mL) and the combined ethyl acetate solution was washed with water and brine. The solution was then dried (Na2SO4), filtered and evaporated. Purification of the residue by flash chromatography on silica gel (5% ethyl acetate/hexanes) gave 7-2 (2.43 g, 98%).
