Procedure
To a mixture of 4-nitrophenyl N-{[(4aR*,6R*,8aR*)-2-{[(tert-butoxy)carbonyl](methyl)amino}-3-cyano-8-methyl-4H,4aH,5H,6H,7H,8H,8aH,9H-thieno[3,2-g]-quinolin-6-yl]carbonyl}-N-propylcarbamate (200 mg) and tetrahydrofuran (3 mL) was added N,N-dimethyl ethylenediamine (0.071 mL) while stirring at room temperature, and the mixture was stirred at the same temperature for 22 hours. The reaction mixture was concentrated under reduced pressure. The residue was purified by aminopropyl silica gel column chromatography (eluent: 0%-5% methanol/ethyl acetate, gradient elution) to give tert-butyl N-[(4aR*,6R*,8aR*)-3-cyano-6-[({[2-(dimethylamino)ethyl]-carbamoyl}(propyl)amino)carbonyl]-8-methyl-4H,4aH,5H,6H,7H,8H,8 aH,9H-thieno-[3,2-g]quinolin-2-yl]-N-methylcarbamate (160 mg).
