Procedure

##STR8## The phenol IV (1.3 g.) was dissolved in benzene (10 ml.), and methyl isocyanate (0.6 g.) and dibutyltin diacetate (two drops) added. The solution was allowed to stand at room temperature for 4 days, then petroleum ether was added to precipitate the carbamate VI, (1.6 g.), m.p. 160°-164° C.

Workup

  1. customto precipitate the carbamate VI, (1.6 g.), m.p. 160°-164° C.
