Participants

Reaction Steps

An ice-cooled, stirred solution of 4-benzyl-5-(6-carboxy-cyclohex-3-enylmethyl)-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (3.0 g) in dichloromethane (70 ml) was treated with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloide (1.61 g), 1-hydroxybenzotriazole and tert-butylamine (1.12 g). The reaction mixture was allowed to stir and warm to ambient temperature during 16 hours. The reaction mixture was then washed sequentially with 2M aqueous hydrochloric acid, 10% aqueous sodium bicarbonate solution, water and saturated aqueous sodium chloride solution, dried (anhydrous magnesium sulfate) and evaporated to give 4-benzyl-5-(6-tert-butylcarbamoyl-cyclohex-3-enylmethyl)-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (322 g, 95%)
