YieldReaction ConditionsOperation in experiment
With tris-(dibenzylideneacetone)dipalladium(0); sodium t-butanolate; tert-butyl XPhos; In toluene; at 80℃; for 14h;Sealed tube; Microwave irradiation; To a solution of 4-fluro-1H-indazole (11.3 mg, 0.083mmol) in toluene (1 mL) in a microwave vial were added 2-(5-bromo-3-pyridinyl)-2-propanol (18 mg, 0.083 mmol), tris(dibenzylideneacetone) palladium (0) (7.6 mg, 8.33 umol), sodium tert-butoxide (12 mg, 0.125 mmol) and 2-di-tert-butylphosphino-2',4',6'- triisopropylbiphenyl (3.5 mg, 8.33 umol). The resulting mixture was sealed and heated to 80 C for 14 hours, then concentrated under reduced pressure. Purification by flash chromatography on silica gel (0% to 50% ethyl acetate/hexanes linear gradient) provided the title compound: LCMS m/z 271.98 [M + H]+; 1H NMR (500 MHz, CD3OD) delta 8.74 - 8.75 (m, 2 H), 8.40 (d, J= 2.4 Hz, 1 H), 8.20 (d, J= 2.7 Hz, 1 H), 7.71 (ddd, J= 4.0, 10.8, 12.8 Hz, 1 H), 7.22 - 7.30 (m, 3 H), 1.65 (s, 6 H).
