Versuchsvorschrift

To a stirred solution of (2-(6-chloro-4-(isopropylamino)pyridin-3-yl)-N-(3-hydroxypropyl)-5-methyloxazole-4-carboxamide (31) (100 mg, 0.283 mmol) in 1,4-Dioxane (10 mL), benzo[c][1,2,5]thiadiazol-5-amine (0.283 mmol, 1 equiv.), Na2CO3 (1.134 mmol, 4 equiv.) and Xanthphos (0.113 mmol, 0.4 equiv.) were added and degassed for 10 min. Pd2(dba)3 (0.113 mmol, 0.4 equiv.) was added and degassed once again for 10 min. Heated the reaction mixture at 115° C. for overnight. The reaction was cooled and filtered through small pad of celite. The filtrate obtained was concentrated to provide crude material. The crude material was purified by column chromatography through silica gel and MeOH: CHCl3 as eluent to afford 2-(6-(benzo[c][1,2,5]thiadiazol-5-ylamino)-4-(isopropylamino)pyridin-3-yl)-N-(3-hydroxypropyl)-5-methyloxazole-4-carboxamide [Example 90]. 1H NMR: 400 MHz, CD3OD: δ 1.42 (d, J=6.40 Hz, 6H), 1.83-1.84 (m, 2H), 2.71 (s, 3H), 3.51 (t, J=1.20 Hz, 2H), 3.72 (t, J=7.20 Hz, 2H), 3.81-3.83 (m, 1H), 6.28 (s, 1H), 7.67 (dd, J=2.00, 9.40 Hz, 1H), 7.89 (dd, J=9.60, 9.20 Hz, 1H), 8.47 (s, 1H), 8.64 (s, 1H). LC/MS: Ascentis Express C18, 5×2.1 mm-2.7 μm; Solvent A=2% ACN: 98% H2O: 10 mM NH4COOH; Solvent B=98% ACN: 2% H2O: 10 mM NH4COOH; gradient 0-100% B over 3 min; retention time: 1.896 min; LCMS (ES-API), m/z 466.0 (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 15 min (23 min run time); Flow rate: 1.0 μL/min; Retention time: 6.335 min; Purity: 98.7%.
