NOVEL CRYSTAL FORMS OF 1-[5-METHANESULFONAMIDOINDOLYL-2-CARBONYL]-4-[3-(1-METHYLETH YLAMINO)-2-PYRIDINYL]PIPERAZINE.

摘要

The present invention relates to two novel crystal forms of a known compound, 1-[5-methanesulfonamidoindolyl-2-carbonyl]-4-[3-(1-methyleth ylamino)-2-pyridinyl]piperazine monomethanesulfonate salt, which are identified by a powder X-ray diffraction spectrum known commonly as the "S" and "T" forms.
