4-Aminopyridine → Carbamic acid, 4-pyridinyl-, phenyl ester

Participants

Reaction Steps

A solution of 4 aminopyridine (0.6 g, 6.37 mmol) in dichloromethane (15 ml) is treated with triethylamine (0.89 ml, 6.37 mmol) followed by phenylchloroformate (0.80 ml, 6.37 mmol) and then stirred at room temperature for 3 days. The reaction mixture is partitioned between dichloromethane and aqueous sodium bicarbonate. The organic phase is dried over magnesium sulphate and evaporated to afford pyridin-4-yl-carbamic acid phenyl ester.
