Anytime obtained is uniform crystal of N- (4-f luorophenyl) -N' -phenyl-N' ' - (pyrimidin-2-ylmethyl) -1, 3, 5-triazine-2, 4, 6-triamine (compound A) and/or N, N' -bis (4-f luorophenyl) -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.
