実験手順

10 ml of diisopropylethylamine is added to a mixture of 3.8 g (21 mmoles) of 4,6-dichloro-5-ethyl-pyrimidine and 4.4 g (15 mmoles) of (1,1-dimethylethyl)-3-amino-N-[(phenylmethoxy)carbonyl]alaninate (prepared according to J. Med. Chem. (2001), 44(8), 1158-1176) in 50 ml of dimethylformamide, then this mixture is heated at 120° C. for 6 hours. Then the dimethylformamide is eliminated under vacuum and the residue is taken up in a mixture of ethyl acetate, water and a saturated solution of sodium bicarbonate. The organic phase is decanted then dried over magnesium sulphate and the solvent is eliminated by evaporation under vacuum. The residue is chromatographed on silicagel eluting with a gradient of 100% heptane to heptane-ethyl acetate 50-50. 4.7 g (Yield=70%) of expected product is obtained in the form of an oil.
