The chemical industry reduces the impact on the environment during synthesis 344-14-9, name is Dimethyl 2-fluoromalonate, I believe this compound will play a more active role in future production and life. 344-14-9
Part B 2-(Difluoromethyl)-5-fluoro-6-hydroxy-4(1 H)-pyrimidinone Sodium metal (0.91 g, 40 mmol) was dissolved in MeOH (100 mL) to form sodium methoxide. 2,2-Difluoroethanimidamide HCI (1 .73 g, 13 mmol) was added followed by dimethyl fluoropropanedioate (2.0 g, 13 mmol). The resulting solution was stirred at 80 C for 3 hours, then cooled to room temperature. Aqueous HCI (6 mL, 6M, 36 mmol) was added and the resulting mixture was concentrated in vacuo. The remaining solid was washed with cold water and filtered yielding 2-(difluoromethyl)-5- fluoro-6-hydroxy-4(1 H)-pyrimidinone (1.43 g, 61 %)
