1136-45-4, 5-Methyl-3-phenylisoxazole-4-carboxylic acid is a Isoxazoles compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
5-Methyl-3-phenylisooxazole-4-carboxylic acid (40 mg, 0.197 mmol), 3-(pyrrolidin-2-ylmethyl)pyridine (50.5 mg, 0.215 mmol), O-(benzotriazol-1-yl)-N,N,N’,N’-tetramethyluronium tetrafluoroborate (86.2 mg, 0.268 mmol) and diisopropylethylamine (25.4 mg, 0.197 mmol) were mixed in dimethylformamide (1.0 mL) and stirred at room temperature. Solvent was evaporated in vacuo, and the residue was taken up in methanol (1 mL), filtered and purified by preparative chromatography. The combined fractions were partitioned between NaHCO3 (sat) and ethylacetate. The organic layer was washed with water and concentrated in vacuo to afford the title compound. HRMS (ESI, pos. ion) m/z calcd for C21H21N3O2: 349.1426, found 349.1693.
As the paragraph descriping shows that 1136-45-4 is playing an increasingly important role.
