Procedure

52 ml (0.53 mole) of isopropyl isocyanate are added dropwise over a period of 20 minutes to a solution of 62.5 g (0.5 mole) of 5-aminoresorcinol in 1000 ml of dioxan, the internal temperature rising to 35° C. The whole is subsequently stirred for 5 hours at room temperature and then 1000 ml of petroleum ether are added whereupon the title compound is precipitated in the form of fine crystals.
