実験手順

To a slurry of 0.044 g 4-chloro-6,7-dihydro-5H-cyclopenta[4,5]thieno[2,3-d]pyrimidine (0.196 mmol) in 1 mL of 100:1 H2O/HCl was added 0.014 g (0.02 mL, 0.106 mmol) diethylamine. The mixture was heated to reflux, and an additional 0.2 mL diethylamine and 1 mL of t-butanol were added and heated continued at reflux for an additional 1 h. TLC (20% EtOAc/80% pet ether) showed complete reaction and the 1H NMR of the isolated material was consistent with the desired product.
