HCID 76639Benzyl isocyanate

Procedure

6 grams of bis-methylsalicyl carbonate and 1.97 grams of benzylamine, corresponding to a 1:1 molar ratio, were dissolved in 20 milliliter of dichloromethane. The solution was stirred at room temperature under atmospheric conditions for 30 minutes to form 2-methoxyphenyl benzylcarbamate. (Isocyanatomethyl)benzene was prepared by pyrolysis of this carbamate as shown in FIG. 6 using the same procedure as in Example 45. The desired isocyanate was observed to be formed.
