FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing 4-{1-[(4-methylphenyl)sulphonyl]-1H-indol-2-yl}but-3-en-2-one derivatives of general formula I:
via temperature control of a mixture of readily available 2-(N-tosylamino)benzhydrol of formula:
,
where the values of R1-R3 are given above, and N-[(furan-2-yl)methyl]-4-methyl benzenesulphamide in acetic acid in the presence of catalytic amounts of hydrochloric acid at temperature of 40°C for 48 hours.
EFFECT: method enables to reduce resinification of the reaction mixture and increases output of end products.
