실험 절차

72 parts by weight of β-naphthol are dissolved in 250 parts by weight of cumene at 80° C. 46.7 parts by weight of methylcarbamyl chloride are stirred into this solution over a period of 10 minutes while nitrogen is simultaneously bubbled through the solution. The reaction is complete after 15 minutes. The hot reaction solution is cooled to 0° C and the precipitated β-naphthyl-N-methylcarbamate is isolated. The yield is 85% of theory.
