NOVEL SALT OF 1,3,5-TRIAZINE-2,4,6-TRIAMINE DERIVATIVE

摘要

Anytime obtained is uniform crystal of N-(4--fluorophenyl)-N'-phenyl-N"-(pyrimidin-2-ylmethyl)-1,3,5--triazine-2,4,6-triamine (compound A) and/or N,N'-bis(4--fluorophenyl)-N"-(pyrimidin-2-ylmethyl)- 1,3,5-triazine-2,4,6-triamine (compound B) as a medicament or a starting material for the preparation of the medicament, and provided are a fumarate of the compound A and/or the compound B having excellent stability and a novel crystal thereof. A salt of the compound A and/or the compound B with fumaric acid enables uniform crystal to be anytime obtained, and thus, it is a compound that is very useful as a medicament or a starting material for the preparation of the medicament having excellent stability.
