Procedure

The mixture of N-(2,6-dichlorobenzoyl)-4-amino-L-phenylalanine methylester (1.0 g), EDC/HCl (783 mg), HOAt (555 mg), triethylamine (747 μL), 4-aminopyrimidine-5-carboxylic acid (417 mg) and dichloromethane (15 mL) was stirred overnight. After diluting the mixture with dichloromethane and washing with saturated sodium bicarbonate water, the organic layer thereof was dried over sodium sulfate and concentrated. The residue was washed with dichloromethane to obtain 145 mg of a crude material of the title compound.
