Reaction Steps

A solution of 413 mg (2.0 mmol) of dicyclohexyldicarbodiimide in 10 ml of dry CH2Cl2 is added while stirring at room temperature to 429 mg (2 mmol) of (2R,3S)-3-nonyloxirane-2-carboxylic acid, 633 mg (2 mmol) of 4-(2-n-octylthiopyrimidin-5-yl) phenol and also 20 mg of 4-dimethylaminopyridine. After stirring for 4 hours at room temperature, the reaction solution is evaporated down in vacuo. After chromatographic purification and recrystallization from n-hexane, 120 mg (12%) of colorless crystals are obtained. The substance exhibits the liquid-crystal phase sequence: X 73 SA 93.5 I.
