Reaction Steps

To a mixture of tert-butyl N-[(4aR*,6R*,8aR*)-3-cyano-6-[({[2-(dimethylamino)ethyl]carbamoyl}(propyl)amino)carbonyl]-8-methyl-4H,4aH,5H,6H,7H,8H,8aH,9H-thieno[3,2-g]quinolin-2-yl]-N-methylcarbamate (160 mg) and ethyl acetate (10 mL) was added a 4 mol/L hydrogen chloride-ethyl acetate solution (5 mL) while stirring at room temperature, and the mixture was stirred at the same temperature for 11 hours. To the reaction mixture was added a 4 mol/L hydrogen chloride-ethyl acetate solution (5 mL) while stirring at room temperature, and then stirred at the same temperature for 13 hours. The solid was collected by filtration to give the title compound (compound 3-1) (116 mg). The structure was illustrated in Table 11.
