Reaction Steps

After adding trifluoroacetic acid to a suspension of 28.5 mg of 4-{[(3-hydroxymethyl-5-methoxyphenyl)-(5-oxo-1-pyrimidin-2-yl-4,5-dihydro-1H-[1,2,4]triazol-3-yl)methyl]amino}benzamidine acetate in 2.85 ml of DMSO, the mixture was concentrated under reduced pressure. The residue was optically resolved using a SUMICHIRAL OA-2500 column, and the first fraction was obtained. This was dissolved in a trifluoroacetic acid:acetonitrile:water=1:50:50 mixed solvent and concentrated, and the first fraction (9.80 mg) of the title compound was obtained as a white solid.
