Reaction Steps

p-Nitrophenylisocyanate (0.1 mole) was added to a solution of 3-pyridylcarbinol (0.1 mole) in 300 ml. of benzene. An exothermic reaction took place and a yellow solid formed. The suspension was heated to reflux and then stirred for 2 hours. The suspension was then cooled and filtered, affording 27 g. of a crude product melting at 230°-231° C. (decomposed). This is a 99% yield of 3-pyridylmethyl N-(4'-nitrophenyl)-carbamate. The product was purified by recrystallization from 2-methoxyethanol (methyl Cellosolve).
