Dimethylformamide → 2-(4-Methoxy-6-methyl-2-pyrimidinyloxy)-3-(2-(3,4-dimethoxyphenyl)ethoxy)-3,3-diphenylpropionic Acid

Participants

Reaction Steps

1 g (2.3 mmol) of 2-hydroxy-3-(2-(3,4-dimethoxyphenyl)ethoxy)-3,3-diphenylpropionic acid was introduced into 10 ml of DMF, and 340 mg of NaH (50% suspension) were added. After the mixture had been stirred for 15 minutes, 526 mg of 4-methoxy-6-methyl-2-methylsulfonylpyrimidine were added, and the mixture was stirred at room temperature for 3 hours. Water was added to the mixture, which was then extracted with ether. The aqueous phase was acidified with 1 N aqueous HCl, extracted with ether and dried over magnesium sulfate. The solvent was distilled off, the residue was purified by MPLC, and 655 mg (52%) of colorless powder were isolated after recrystallization from ether/n-hexane.
