Procedure

To a solution of 1,2,3,4-tetrahydro-3-methyl-1-(2-methylpropyl)-6-(1-naphthalenylmethyl)-2,4-dioxothieno[2,3-d]pyrimidine-5-carboxylic acid (50 mg) and 2-aminoethanol (14 μl) in dichloromethane (2 ml) was added 1-hydroxybenzotriazole hydrate (48 mg) followed by 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (45 mg). The reaction mixture was stirred at room temperature for 18 hours then hydrochloric acid (1M, 20 ml) was added and the mixture was extracted with ether (30 ml). The organic extracts were washed with water, then with 1M sodium hydroxide solution, dried over anhydrous magnesium sulfate, filtered and evaporated under reduced pressure. The residue was recrystallised from ethyl acetate:isohexane to give the title compound (28 mg).
