実験手順

The process is performed as in Example 2, starting with 5.1 g of 2-amino-2-(3-nitrophenyl)-1-ethanol in 170 cm3 of ethanol containing 85 cm3 of dichloromethane and 4.6 cm3 of tert-butyl isothiocyanate, at a temperature in the region of 20° C. for 3 days and then at a temperature in the region of 60° C. for 7 hours. After addition of a further 0.35 cm3 of tert-butyl isothiocyanate and 16 hours at a temperature in the region of 60° C., an identical work-up gives 5.7 g of N-(tert-butyl)-N′-[2-hydroxy-1-(3-nitrophenyl)ethyl]thiourea in the form of an ocher-colored solid melting at 162° C.
