| Reactant | 3-(2,3-Difluoro-phenyl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester | HCID 68442551 | — |
| Reactant | Ethyl 3-(2-fluorophenyl)-5-methylisoxazole-4-carboxylate | HCID 68442729 | — |
| Product | [3-(2,3-Difluoro-phenyl)-5-methyl-isoxazol-4-yl]-methanol | HCID 68458483 | 35% |
Reaction Steps
As described for example 84d, 3-(2,3-difluoro-phenyl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester (16.0 g, 59.9 mmol) was converted, instead of 3-(2-fluoro-phenyl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester, to the title compound (4.7 g, 35%) which was obtained as a yellow oil. MS: m/e=226.2 [M+H]+.
