実験手順
To a stirred solution of tert-butyl 4-((5-(6-(benzo[d]thiazol-6-ylamino)-4-(isopropylamino)pyridin-3-yl)-1,3,4-oxadiazol-2-yl)amino)piperidine-1-carboxylate (Example 111) (250 mg, 0.3 mmol) in DCM (10 mL), Ether.HCl (10 mL) was added at −10° C. Stirred the reaction mixture at 0° C. for 30 min. Reaction temperature was slowly brought to room temperature. The reaction mass was concentrated under reduced pressure to dryness. The material obtained was purified by prep. HPLC to afford the title compound, N2-(benzo[d]thiazol-6-yl)-N4-isopropyl-5-(5-(piperidin-4-ylamino)-1,3,4-oxadiazol-2-yl)pyridine-2,4-diamine 1H NMR: 400 MHz, CD3OD: δ 1.37 (d, J=6.40 Hz, 6H), 1.90-2.00 (m, 2H), 2.33-2.37 (m, 2H), 3.20-3.29 (m, 2H), 3.50-3.53 (m, 2H), 3.87-3.93 (m, 2H), 6.28 (s, 1H), 7.63 (dd, J=1.20, 8.40 Hz, 1H), 8.21-8.27 (m, 3H), 9.54 (bs, 1H). LC/MS: Purospher@star RP-18, 4×55 mm, 3 μm; Solvent A=10% ACN: 90% H2O: 20 mM NH4OAc; Solvent B=90% ACN: 10% H2O: 20 mM NH4COOAc; gradient 0-100% B over 1.5 min (3.2 min run time); retention time: 1.277 min; LCMS (ES-API), m/z 451.2 (M−H). HPLC: Sunfire C18 (150×4.6 mm), 3.5 micron; Solvent A=5% ACN: 95% H2O: 0.05% TFA pH=2.5; Solvent B=95% ACN: 5% H2O: 0.05% TFA pH=2.5; gradient 0-100% B over 30 min (36 min run time); Flow rate: 1.0 μL/min; Retention time: 8.965 min; Purity: 98.1%.
