Process for the preparation of 5-formylphthalide |
| abstract |
There is described a process for the preparation of 5-formylphthalide by hydrogenation of a halide of 5-carboxyphthalide, dissolved in a dipolar aprotic solvent, in the presence of a catalyst. Furthermore, the use of 5-formylphthalide in the preparation of citalopram is described. |
