Synthetic Route of 1245772-13-7<\/a>,Some common heterocyclic compound, 1245772-13-7, name is Methyl 1-(2,2,2-trifluoroethyl)-1H-pyrazole-3-carboxylate, molecular formula is C7H7F3N2O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

Example 256: 2-N-Methyl-2-N-phenyl-6-{5-[1-(2,2,2-trifluoroethyl)-1 H-pyrazol-3-yl]-1 ,2,4- oxadiazol-3-yl}-1 ,3,5-triazine-2,4-diamine (Method 12)Methyl 1-(2,2,2-trifluoroethyl)-1 H-pyrazole-3-carboxylate (Intermediate 204, 0.312 g, 1.5 mmol) was dissolved in a mixture of THF (2 mL), MeOH (2 mL) and water (1 mL); lithium hydroxide (0.188 g, 4.5 mmol) was added and the mixture was stirred at roomtemperature for 16 h. The mixture was concentrated, the residue dissolved in water (1 mL) and the mixture was neutralised. This was extracted with EtOAc (2 x 10 mL), the organic extracts were dried over sodium sulfate and concentrated under vacuum. The crude material was washed with pentane (2 x 10 mL) to afford 1-(2,2,2-trifluoroethyl)-1 H- pyrazole-3-carboxylic acid (0.200 g, 69%). 2-N-methyl-2-N-phenyl-6-{5-[1-(2,2,2- trifluoroethyl)-1 H-pyrazol-3-yl]-1 ,2,4-oxadiazol-3-yl}-1 ,3,5-triazine-2,4-diamine was then prepared from 1-(2,2,2-trifluoroethyl)-1 H-pyrazole-3-carboxylic acid (0.159 g, 0.820 mmol) and 4-amino-N-hydroxy-6-[methyl(phenyl)amino]-1 ,3,5-triazine-2- carboximidamide (prepared in an analogous manner to Intermediate 1 , 0.125 g, 0.483 mmol) according to the method described for Example 251 to afford the title compound (0.110 g, 55%).<\/p>\n

The synthetic route of 1245772-13-7 has been constantly updated, and we look forward to future research findings.<\/p>\n
