Abstract RU 2417986 C2

FIELD: chemistry.

SUBSTANCE: invention relates to crystalline forms of the tartrate of N-(4-fluorobenzyl)-N-(1-methylpiperidin-4-yl)-N'-(4-(2-methylpropyloxy)phenylmethyl)carbamide of formula (IV)

, where the crystalline form is an at least 80% pure crystalline form of C, the powder X-ray pattern of which includes peaks corresponding to values d in angstrom - approximately 10.7, approximately 4.84, approximately 4.57 and approximately 3.77. The invention also relates to methods of producing crystalline forms in claim 1, a pharmaceutical composition, a method of administering a compound of formula (I) to a recipient, a method of inhibiting monoamine receptor activity, as well as use of compounds in claim 1.

EFFECT: obtaining a novel compound having monoamine receptor inhibiting or inverse agonist activity.
