실험 절차

To a solution of 0.16 g of ethyl (4-{[3-(4-tert-butylphenyl)-5,5-dimethyl-2,4-dioxoimidazolidin-1-yl]methyl}pyridin-2-yl)-carbamate obtained in stage a) below in 2 mL of tetrahydrofuran are added successively 0.368 mL of N-methylcyclopentylamine and 0.512 mL of triethylamine. The reaction mixture is heated by microwave at 130° C. for 3 hours and then concentrated under reduced pressure. The residue is purified by chromatography on a column of silica, eluting with a mixture of ethyl acetate and cyclohexane (60/40 by volume) to give 0.048 g of 3-(4-{[3-(4-tert-butylphenyl)-5,5-dimethyl-2,4-dioxoimidazolidin-1-yl]methyl}pyridin-2-yl)-1-cyclopentyl-1-methylurea, the characteristics of which are as follows:
