Sodium hydride → HCID 15295197, compound

Participants

Reaction Steps

To a solution of dimethyl 4-cyano-4-(3-cyclopropylmethoxy-4-methoxyphenyl)pimelate (10.4 g, 26.7 mmol) in dry 1,2-dimethoxyethane (500 mL) under an argon atmosphere was added sodium hydride (80% dispersion in mineral oil, 2.5 g, 31.2 mmol). The resulting mixture was refluxed for 4 h, cooled to room temperature and quenched with water. The mixture was partitioned between ethyl acetate and acidic water, extracted three times, the organic layer was dried (magnesium sulfate) and the solvent was removed in vacuo. The product was purified by flash chromatography, eluting with 2:1 hexanes/ethyl acetate, to provide an oil (9 g, 95%).
