How is 1-(isocyanatomethyl)-4-methoxybenzene (CAS: 56651-60-6) typically synthesized?

1-(isocyanatomethyl)-4-methoxybenzene is typically synthesized by the reaction of 4-methoxybenzylamine with phosgene or carbon dioxide in the presence of a catalyst such as N,N-dimethylformamide (DMF). The process involves the formation of a carbamate intermediate, which is then hydrolyzed to yield the target compound. The yield is generally good, and the selectivity is high.
