As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 769-28-8, name is 4,6-Dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile, molecular formula is C8H8N2O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Application In Synthesis of 4,6-Dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile
To a solution of 4,6-dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (10.0 g, 67.5 mmol) in MeOH (1.50 L) and conc. HCl (30 mL) was added 10% Pd(OH)2 (19 g) under N2 atmosphere. The N2 gas was displaced by H2 gas and the mixture was stirred for 26 hours at RT under hydrogen atmosphere. The H2 gas was displaced by N2 gas. The mixture was filtered through Celite, washed with MeOH and concentrated. The residue was triturated with EtOH, collected with Buchner funnel, and dried under vacuum pressure to give the titled compound as a white solid (11.5 g, 90%). 1H NMR (400 MHz, DMSO-d6): delta ppm 11.86 (brs, 1H), 5.98 (s, 1H), 3.78 (m, 2H), 2.20 (s, 3H), 2.16 (s, 3H).
With the rapid development of chemical substances, we look forward to future research findings about 769-28-8.
