Pyridine → Phenyl isoquinolin-5-ylcarbamate

Participants

Reaction Steps

To 5-aminoisoquinoline (2.7 g) were added phenyl chloroformate (2.85 ml), pyridine (2.0 ml) and tetrahydrofuran (50 ml), and the mixture was stirred for 3 hrs. The reaction mixture was diluted with dichloromethane, and washed with water and saturated aqueous sodium hydrogen carbonate. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated. Diethyl ether was added to the residue, and the precipitate was collected by filtration to give the title compound (3 g).
