Participants

Reaction Steps

A solution of 1.0 g (2.5 mmol) of 2-(4,6-dimethylpyrimidin-2-yloxy)-3-(2-aminoethoxy)-3,3-diphenylpropionic acid in 10 ml of methylene chloride was successively admixed at room temperature with 0.35 g (2.7 mmol) of N-ethyldiisopropylamine, 0.03 g (0.2 mmol) of dimethylaminopyridine and 0.54 g (2.7 mmol) of 3,4-dimethoxybenzoyl chloride. The mixture was stirred at room temperature for 4 days and then diluted with diethyl ether and extracted with 1M hydrochloric acid and 1M aqueous sodium hydroxide solution, and the combined alkaline phases were made acidic and extracted with ether. The organic phase was dried over sodium sulfate, the solvent was distilled off and the residue (0.9 g) was chromatographed over silica gel (methylene chloride/methanol 9:1). Yield: 280 mg of a white foam.
