| titleOfInvention | Production of Arylpyrrole Compounds in the Presence of DIPEA Base |
| abstract | The present invention relates to a method for producing a compound of formula (I), comprising the step A of reacting a compound of formula (II) with 2,3-dihalopropionitrile or 2-haloacrylonitrile in the presence of DIPEA. It also relates to a process for producing a compound of formula (III) comprising step B of reacting a compound of formula (I) with Br2 in the presence of DIPEA. It also relates to a method C for producing a compound of formula (IV), comprising bringing the compound of formula ( III ) with bis(C 1 -C 4 alkoxy)methane and POCl or a mixture comprising POCl and DMF in the presence of DIPEA Step C of the reaction. 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). |
