실험 절차

5-(3-Amino-cyclohexyl)-9-chloro-3-methyl-5H-isoxazolo[4,3-c]quinolin-4-one hydroiodide (70 mg, 0.19 mmol) was combined with EDC (47 mg, 0.25 mmol), 1-hydroxy-7-azabenzo-triazole (34 mg, 0.25 mmol), N,N-diisopropylethyl amine (0.10 mL, 0.58 mmol), DMAP (5 mg, cat.), and N-benzylglycine hydrochloride (50 mg, 0.25 mmol) in DMF(6 mL) and the mixture stirred overnight at rt. The mixture was then concentrated in vacuo and the residue taken up in chloroform/MeOH and the organic solution washed with aqueous NaHCO3. The organic solution was dried over Na2SO4 and concentrated in vacuo. The residue was loaded onto a silica gel column and eluted with MeOH/CH2Cl2, which allowed for the recovery of 32 mg (35%) of the free base. This material was dissolved in minimal EtOAc and treated with excess diethyl ether/hydrochloric acid. Concentration of this mixture to dryness allowed for quantitative recovery of the hydrochloride salt as an off white solid. MS(ES): (M+1)+ 479.1, 481.2.
