Procedure
Incremental portions of 3.6 g of sodium hydride (50% strength in white oil) is added to a solution of 21 g of 4,5-bis(4-methoxyphenyl)imidazole in 75 ml of absolute dimethylformamide. The mixture is stirred for another 30 minutes, and then 6.3 ml of 1-chloromethylmethyl ether in 35 ml of dimethylformamide is added dropwise. After 30 minutes the mixture is poured on ice water, the product is taken up in chloroform, the organic solution is washed with water, dried over sodium sulfate, and concentrated to dryness under vacuum. The residue is crystallized from benzene/hexane, thus obtaining 18.31 g of 4,5-bis(4-methoxyphenyl)-1-methoxymethylimidazole, mp 99°-101°.
