Versuchsvorschrift

2-tert-Butyl-4-[(3-methoxypropyl)amino]-6-oxo-1,6-dihydropyrimidine-5-carboxylic acid (280 mg), tert-butyl (3S,5R)-3-[(2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (250 mg) and N,N-diisopropylethylamine (640 mg) were dissolved in 1,2-dichloroethane (10 ml), chloro-N,N,N′,N′-tetramethylformamidinium hexafluorophosphate (420 mg) was added and the mixture was stirred at room temperature for 3 hr. The reaction mixture was concentrated, and diluted with aqueous calcium carbonate solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was dissolved in TFA (1 ml), and the mixture was stirred at room temperature for 0.5 hr. The reaction mixture was concentrated and purified by HPLC to give the object compound (15.8 mg).
