실험 절차

2,4-dichloro-6-[3-(trimethylsilyl)-propyl]pyrimidine (1 gram), L-leucine-3-ethoxypropylamide hydrochloride (1 gram) and N,N-diisopropylethylamine (2.3 mL) were stirred for 17 h in 20 mL dimethyl sulfoxide at 55° C. The solution was cooled to room temperature and diluted with ethyl acetate (100 mL), then washed 4 times with 100 mL aliquots of a saturated aqueous solution of sodium chloride, dried over magnesium sulfate, filtered, and the solvents were removed in vacuo. Silica gel chromatography (heptane/ethyl acetate 3/1) provided 978 mg of 2-(2-chloro-6-[3-trimethylsilylpropyl]pyrimidin-4-ylamino)-4-methyl-pentanoic acid (3-ethoxypropyl)amide.
