YieldReaction ConditionsOperation in experiment
With potassium tert-butylate; In 1,4-dioxane; at 130℃; for 0.166667h; Solid potassium-tert-butoxide (325 mg, 2.9 mmol) was added to a dioxane solution (7 mL) of <strong>[138564-58-6]2-amino-5-methyl-thiophene-3-carbonitrile</strong> (2.0 g, 14.5 mmol) and 2-furonitrile (1.3 g, 14.5 mmol). The resulting mixture was heated at 130 0C for 10 minutes. The dark slurry was cooled to room temperature, diluted with THF, and dry packed onto silica gel. The material was the purified via column chromatography to give 1.6 g of the title compound.

YieldReaction ConditionsOperation in experiment
75% With Pd(2+)*2C5F9O2(1-); trifluoroacetic acid; 6-methyl-2,2'-bipyridine; In tetrahydrofuran; water; at 130℃; for 1h;Microwave irradiation; General procedure: A 2 mL microwave vialwas charged with 6-methyl-2,2'-bipyridine (16.3 mg, 0.096 mmol), Pd(O2CCF3)2(26.6 mg, 0.08 mmol) and 500 muL THF. After stirring at room temperature for 5minutes, <strong>[123843-65-2]2,6-difluoro-4-methoxybenzoic acid</strong> (188.1 mg, 1 mmol), nitrile (5mmol), water (50 muL) and TFA (77 muL, 1 mmol) were added and the mixture heated inthe microwave for 1 hour at 130 C. Themixture was diluted with DCM (15 mL) and 0.1 M NaOH (15 mL), the phases wereseparated and extracted with DCM (2 ×15 mL), dried with Na2SO4, filtered and concentratedunder reduced pressure. Purification by flash chromatography afforded ketones 3p,3x or 3ac in the yields statedin Table 3.
