Procedure

To a solution of N-ethyl-N′-[3-(dimethylamino)propyl]carbodiimide (37 mg), 1-hydroxybenzotriazole (26 mg) and 4-(3,4-dimethyloxyphenyl)butanoic acid (36 mg) in dichloromethane (6 ml) was added 6-(4-aminophenylmethyl)-3-methyl-1-(2-methylpropyl)thieno[2,3-d]pyrimidine-2,4-(1H,3H)-dione (45 mg) in dichloromethane (2 ml). The reaction mixture was stirred overnight and then washed with half saturated sodium hydrogen carbonate and extracted into ethyl acetate. The organic layer was dried over magnesium sulfate, evaporated and the residue was purified by normal phase HPLC (isohexane:ethyl acetate 50-0:50-100) to give the title compound (19 mg) as a foam.
