Reaction Steps

Furo[2,3-c]isoquinolin-5(4H)-one (55 mg, 0.27 mmol) was dissolved in a mixture of dry dimethylformamide (1 ml) and dry acetonitrile (2 ml) and treated with N,N-dimethyl(methylene)ammonium chloride (1 mmol) prepared according to known procedure (Kinast G. et al. Angew. Chem. Int. Ed. Engl. 1976, 15(4), 239-240; Bohme H. et al. Chem. Ber. 1960, 93, 1305). The reaction mixture was refluxed overnight, and the resulting precipitate was filtered and washed with dry diethyl ether to give the title compound. Yield: 65%.
