Abstract
The present invention provides a process for producing an isocyanate compound such as 3-methyl-2-methoxymethyl-1-isocyanate benzene and the like. By reacting 3-Methyl-2-methoxymethyl aniline and the like with phosgene in the presence of a tertiary amine at 10° C. to 14° C. in one or more solvents selected from the group consisting of toluene and xylene, isocyanate compounds such as 3-methyl-2-methoxymethyl-1-isocyanate benzene and the like can be produced at high yield.
