4(1H)-Pyrimidinone, 2-methyl- (8CI,9CI) Use and Manufacturing
The intermediate hydroxyethyl acrylate salt prepared in the previous step is added with an appropriate amount of methanol to just dissolve, and the catalyst 3A molecular sieve is added.Into the hydrazine hydrochloride 8.7g (0.09mol) heated to 90 C reflux 3h, cooled to room temperature, Evaporate the remaining solvent in the mixture, add an appropriate amount of pure water until the mixture just dissolves, adjust the pH to 7 with 1 mol/L dilute hydrochloric acid, and evaporate the liquid on a rotary evaporator.Add 90% methanol solution, precipitate solid sodium chloride, suction filter to remove sodium chloride impurities, The mother liquor was evaporated to dryness and anhydrous methanol was added to wash away the unreacted guanidine hydrochloride. The resulting
