Potassium Carbonate → 6-Ethoxycarbonylamino-1-methyl-3,4-dihydroisoquinoline

Participants

Reaction Steps

Using 1.0 g of N-acetyl-N-(3-ethoxycarbonylaminophenethyl)amine (Preparation Example 30), cyclization reaction was conducted according to the procedure described in Heterocycles 31(2), 341 (1990). After the completion of the reaction, the reaction mixture was poured onto ice, the mixture was basified with potassium carbonate, and extracted with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate and the solvent was evaporated, to give the title compound as brown oil.
