Reaction Steps

A mixture of 1,2,3,4-tetrahydro-1-naphthylamine (10.01 g) and ether (100 ml) is stirred under a nitrogen atmosphere and a solution of benzoyl isocyanate (9.99 g) in ether (90 ml) is added dropwise. After the addition is completed, the mixture is stirred for 0.5 hour and cooled in ice. The product is collected and washed with cold ether (50 ml) to afford 15.7 g of the title compound, m.p. 166° to 169° C. Recrystallization from acetone affords 13.61 g, m.p. 171° to 173° C.
