Versuchsvorschrift

To a mixture of methyl N-methylcarbamate (0.89 g, 0.01 mole) and 2-sec butylphenol (1.5 g, 0.01 mole) in dichloroethane (10 ml), a solution of phosphorus tribromide (2.7 g, 0.01 mole) in dichloro-ethane (6 ml) was added and the mixture was refluxed for eight hours. It was then worked up and purified as described earlier to give 2-sec butylphenyl N-methylcarbamate of the formula (III).
