Participants

Reaction Steps

2.4 g (9.62 mmol) of (RS)-3-(4-cyclohexyl-phenylamino)-propane-1,2-diol were dissolved in 50 ml of toluene, treated with 1.25 g (10.6 mmol) of diethyl carbonate and 0.4 ml of a 1 molar sodium methylate solution in methanol and stirred overnight at an oil bath temperature of 110°. The solvent was distilled off in a water-jet vacuum and the residue was treated with water and 1N hydrochloric acid and extracted with ethyl acetate. The organic phase was washed with water, dried over magnesium sulfate and the solvent was distilled off. 1.4 g of product in the form of yellowish crystals were obtained from ethyl acetate/hexane. A further 0.9 g of pure product was obtained from the mother liquor. M.p.: 167°-167.5°.
