| titleOfInvention | Process for preparing 2,2-difluoroethylamine starting from prop-2-en-1-amine |
| abstract | A process for preparing 2,2-difluoroethylamine of the formula (I) CHF 2 CH 2 NH 2 comprising steps (i) and (ii). In step (i), 2,2-difluoro-1-halogenethane represented by the formula (II) CHF 2 —CH 2 Hal, wherein Hal means chlorine, bromine or iodine, is preferably In the presence of an acid scavenger, it is reacted with prop-2-en-1-amine represented by the formula (III) to give N- (2,2-difluoroethyl) propa-form represented by the formula (IV). 2-ene-1-amine is produced. In step (ii), the allyl group is removed from N- (2,2-difluoroethyl) prop-2-en-1-amine represented by formula (IV) obtained in step (i), 2,2-difluoroethylamine represented by (I) or a salt thereof is produced.
