2-Hydroxy-4,6-dimethylpyrimidine Use and Manufacturing
IM06: 4, 6-Dimethyl-pyrimidin-5-ylamineStep 1:To a solution of urea (20.0 g, 333.3 mmol) and acetyl acetone (33.3 g, 333.3 mmol) in EtOH (166 mL) was added concentrated aqueous HCl (45 mL). The mixture was stirred at 80° C. for 24 h. The mixture was then cooled to room temperature, filtered and the remanens washed with cold EtOH to give 4, 6-dimethyl-pyrimidin-2-ol as a colorless solid (40 g, 97percent). 1H NMR (DMSO-d6, 400 MHz) δ 7.35 (1H, s), 2.43 (6H, s).To a solution of urea (20.0 g, 333.3 mmol) and acetyl acetone (33.3 g, 333.3 mmol) in EtOH (166 mL) was added concentrated aqueous HCI (45 mL).
