| titleOfInvention | Production of arylpyrrol compounds in the presence of dipea base |
| abstract | The invention relates to a process for the production of compounds of formula (I), comprising Step A of reacting compounds of formula (II) with 2,3-dihalopropionitrile or 2-haloacrylonitrile in the presence of DIPEA. It also relates to a process for the production of compounds of formula (III), comprising Step B of reacting compounds of formula (I) with Br2 in the presence of DIPEA. It also relates to a process C for the production of compounds of formula (IV), comprising Step C of reacting compounds of formula (III) with di(C1-C4-alkoxy)methane and either POCl3, or a mixture comprising POCl3 and DMF, in the presence of DIPEA. It also relates to the use of DIPEA as a base in the production of compounds of formula (I), compounds of formula (III) or compounds of formula (IV). |
