Ethyl isocyanate → HCID 70150448, compound

Participants

Reaction Steps

To a mixture of 2-[4-(1-pyrazolyl)methylphenoxy]ethanol (produced in Reference Production Example 3 described below) (500 mg), triethylamine (255 mg) and dry toluene (20 ml) was added dropwise an anhydrous toluene solution (1 ml) of ethyl isocyanate (179 mg). This mixture was then stirred at room temperature overnight, and concentrated under reduced pressure. The residue was subjected to silica gel chromatography, which afforded 87 mg of ethylcarbamic acid 2-[4-(1-pyrazolyl)methylphenoxy]-ethyl ester (compound 37). Yield, 13%.
