実験手順

3-aminothiophene-2-carboxylic acid methylester (1.6 g, 10 mmol) was added to formamide (3.4 ml), and the mixture was stirred at 200° C. for 2 hours. The reaction mixture was returned to room temperature, and water was added thereto, which was extracted with chloroform. The solid obtained by distilling off the solvent under reduced pressure was washed with ethyl acetate to obtain 4-hydroxythieno[3,2-d]pyrimidine (60 mg, 0.39 mmol).
