Versuchsvorschrift

To a solution of HCl in EtOAc (4M, 5 mL, 20 mmol) was added slowly tert-butyl-3-(1-methyl-2-oxo-2,3,5,6-tetrahydro-1H-[1,2,4]triazino[4,3-a]quinolin-9-ylamino)azetidine-1-carboxylate (0.022 g, 0.057 mmol) and the reaction mixture was stirred at ambient temperature for 2 h. The solution was concentrated in vacuo to give 9-(azetidin-3-ylamino)-1-methyl-5,6-dihydro-1H-[1,2,4]triazino[4,3-a]quinolin-2(3H)-one hydrochloric acid (0.015 g, 95%). LC/MS (Table 1, Method 5) Rt=2.252 min; MS m/z: 286 [M+H]+.
