YieldReaction ConditionsOperation in experiment
22 g With copper(l) iodide; potassium carbonate; sodium iodide; N,N`-dimethylethylenediamine; In N,N-dimethyl-formamide; at 100℃; for 96h;Inert atmosphere; Step E: Preparation of 5-[l-(6-Methoxy-2-methyl-3-pyridinyl)-lH-pyrazol-3-yl]-2- methylbenzonitrile A flask was charged with 2-methyl-5-(lH-pyrazol-3-yl)benzonitrile (i.e. the product of Step D) (15.5 g, 82.8 mmol), <strong>[126717-59-7]3-bromo-6-methoxy-2-methylpyridine</strong> (18.4 g, 91.1 mmol), copper(I) iodide (1.58 g, 8.28 mmol), potassium carbonate (22 g, 166 mmol), sodium iodide (13.7 g, 91.1 mmol), and N,N'-dimethylformamide (200 mL) under a nitrogen atmosphere. The mixture was degassed by alternating vacuum and filling with nitrogen for 3 cycles, then N,N '-dimethyl ethylenediamine (DMEDA) (2.0 mL, 19 mmol) was added via syringe and the mixture was heated to 100 C and stirred for 4 days under nitrogen. The hot solution was diluted with water (400 mL) and cooled to room temperature. The resultant slurry was filtered and washed with water. The crude solid was stirred in a mixture of methanol (100 mL) and 10% ammonia (200 mL) at 50 C for 30 min. The mixture was cooled to room temperature and the slurry was filtered and dried under vacuum to afford the title compound (22 g) as a solid. lU NMR (500 MHz, CDC13) delta 8.09 (s, 1H), 7.97 (m, 1H), 7.60 (s, 1H), 7.56-7.59 (m, 1H), 7.36 (d, 1H), 6.74 (d, 1H), 6.68 (d, 1H), 3.98 (s, 3H), 2.58 (s, 3H), 2.39 (s, 3H).
