Sodium hydride → HCID 66704071, compound

Participants

Reaction Steps

To a 0° C. solution of 3-(diethoxy-phosphorylmethyl)-benzoic acid methyl ester (1.2 g, 4 eq) in diethyl ether (15 mL) is added sodium hydride (0.17 g, 4 eq). After 1 h, 2-chloro-4-[3-(2,6-dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-benzaldehyde (0.44 g, 1 eq) in diethyl ether (5 mL) is added and the reaction is stirred overnight. Upon completion, the reaction is quenched with water. The aqueous solution is acidified with 1N HCl and extracted two times with ethyl acetate. The organic layers are combined, washed with brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue is purified via filter chromatography eluting with 10% ethyl acetate:toluene to give 3-(2-{2-Chloro-4-[3-(2,6-dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-phenyl}-vinyl)-benzoic acid methyl ester (0.459 g).
