実験手順
(4R/S)-4-({4-[(2,3-dihydro[1,4]dioxino[2,3-c]pyridin-7-ylmethyl)amino]-1-piperidinyl}methyl)-3,4-difluoro-4,5-dihydro-7H-pyrrolo[3,2,1-de]-1,5-naphthyridin-1-one (43 mg) was resolved by preparative chiral HPLC into the two enantiomers E1 and E2 using a Chiralpak AD-H column, eluting with 50:50:0.1 acetonitrile:methanol:isopropylamine, affording enantiomers E1 (first eluting) and E2 (second eluting) which were converted to the mono hydrochloride salts by dissolving in methanol, adding 1 equivalent of aqueous 6.0N HCl and evaporating to dryness.
