실험 절차

To tert-butyl (1-(2-(7-formyl-[1,2,4]triazolo[4,3-a]pyridin-3-yl)quinolin-8-yl)piperidin-4-yl)methylcarbamate (Example 11, steps A-K; 10 mg, 0.021 mmol) in DCM/MeOH (1 mL/1 mL) was added EtNH2 (0.1 mL, 2M in THF) and HOAc (0.2 mL), followed by NaB(OAc)3H (13 mg, 0.062 mmol). The reaction mixture was stirred for 5 hours at ambient temperature and then concentrated. The crude material was purified by silica gel chromatography (DCM/MeOH/NH4OH 20:1:0.1) to provide the desired product (4 mg). MS APCI (+) m/z 343 (M+1) detected.
