The process is performed as in Example 2, starting with 5 g of (R)-(+)2-amino-3-phenyl-1-propanol in 50 cm3 of ethanol and 5.7 g of tert-butyl isothiocyanate at a temperature in the region of 20° C. for 16 hours. After an identical work-up, 8.7 g of N-(tert-butyl)-N′-[(1R)-2-hydroxy-1-(phenylmethyl)ethyl]thiourea are obtained in the form of a white solid melting at 107° C.
