Reaction Steps
5-Amino-2-nitro-4-[(R)-2-octyloxy]benzoic acid (0.06 g), 0.1 g of 4-(5-heptyl-2-pyrimidinyl)phenol and 0.04 g of 4-(dimethylamino)pyridine were dissolved in 10 ml of dichloromethane and the solution was treated portionwise within 10 minutes with 0.07 g of N,N'-dicyclohexylcarbodiimide while stirring. The mixture was stirred at room temperature for 40 hours, filtered and concentrated. Chromatography of the residue on silica gel with ethyl acetate/dichloromethane (vol. 1:8) and recrystallization from diethyl ether/hexane (vol. 1:1), gave 0.09 g of 4-(5-heptyl-2-pyrimidinyl)phenyl 5-amino-2-nitro-4-[(R)-2-octyloxy]benzoate of melting point 105° C.
