2,6-Dimethyl-4-pyridinol Use and Manufacturing

2, 6-Dimethyl-pyridin-4-ol (90) EPO 2, 6-Dimethyl-pyridin-4-ol (90); EPO Synthesis of Compound Rl.; 2, 6-Dimethyl-pyridin-4-ol (90); Five separate batches of dehydroacetic acid (1.5 g, 8.92 mmol) are each suspended in cone, ammonia (4 mL) and irradiated at 120°C for 20 minutes (150 W, Discover.(R). System microwave reactor by CEM Corporation, Matthews, North Carolina, USA) in the microwave. Once cooled, the solutions are combined and evaporated to dryness to afford the title compound.Yield: 5.91 g (108percent) (at) 73percent purity by LC/MS. The remaining mass balance is unreacted dehydroacetic acid.LC/MS t
