Reaction Steps

700 mg of NaOEt (10 mmol; 1.0 equiv) was added to 6 mL of abs. EtOH. To this solution was added, with stirring, 2 g of ethyl 2-keto-cyclooctylcarboxylate (10 mmol; 1.0 equiv) and 1 g of thiourea (13 mmol; 1.3 equiv). The mixture was refluxed for 6 hours. After cooling, the mixture was poured onto ice and acidified with hydrochloric acid. 1.33 g of 2-mercapto-5,6,7,8,9,10-hexahydrocycloocta[d]-pyrimidine-4-ol (63% yield) was obtained as a white solid.
