The carbonylation reaction is conducted in the same manner as in Example 1 except that 25 mmol of cyclohexylamine, 86 g of α-naphthol, 1.5 g of Rh/C having 5% Rh carried on activated charcoal and 1 mmol of tetraethylammonium iodide are employed. As a result, the yields of cyclohexyl isocyanate and α-naphthyl cyclohexyl carbamate are 58% and 10%, respectively.
