실험 절차

Using diethyl 5-amino-3-methylthiophene-2,4-dicarboxylate and benzyl N-(2-cyanoethyl)carbamate, the ring-closing reaction was carried out similarly to Production Example 1. Successively the hydrolysis was carried out similarly to Example 1, to provide 2-(2-benzyloxycarbonylaminoethyl)-5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylic acid.
