Procedure

This compound may be prepared as obtained in stage c) of Example 9, but starting with 100 mg of 3-(4-tert-butylphenyl)-5,5-dimethyl-1-[(2-thioxo-2H-[1,2,4]oxadiazolo[2,3-a]pyridin-7-yl)methyl]imidazolidine-2,4-dione obtained in stage b) of Example 9, 2 mL of dimethyl sulphoxide and 60 mg of cyclopentanamine. After chromatography on a column of silica, eluting with a mixture of diethyl ether/ethyl acetate (gradient from 100/0 to 0/100 by volume), 33 mg of 1-(4-{[3-(4-tert-butylphenyl)-5,5-dimethyl-2,4-dioxoimidazolidin-1-yl]methyl}pyridin-2-yl)-3-cyclopentylurea are obtained in the form of a white powder, the characteristics of which are as follows:
