To a solution of 2-isopropoxyphenol (1.52 g, 0.01 mole) and ethyl N-methylcarbamate (1.03 g, 0.01 mole) in dichloroethane (10 ml, was added phosphoryl chloride (1.54 g, 0.01 mole) and refluxed for six hours. The reaction mixture was worked up as described earlier to give 2-isopropoxyphenyl N-methylcarbamate of the formula (VI) as a solid, crystallised from pet. ether, m.p. 89° C. to 90° C.
