4-Tolylbiguanide reacts with cinnamaldehyde in ethanolic hydrochloric acid at pH 1 to yield 4,6-diamino-1,2-dihydro-1-(4-methylphenyl)-2-styryl-1,3,5-triazin (5.HCl). The structure was established on the basis of NMR-techniques including two-dimensional experiments. A single crystal X-ray crystal structure analysis of 5 was carried out at 100 K: C18H19N5.HCl, M(r) = 341.84, triclinic, P 1, a = 9.740(4), b = 10.055(4), c = 10.077(2) angstrom, alpha = 75.60(2)-degrees, beta = 88.92(2)-degrees, gamma = 66.61(2)-degrees, V = 873.8(5) angstrom 3, Z = 2, d(x) = 1.299 g/cm3m, mu = 0.22 mm-1, R = 5.57%, R(w) = 5.56% (2451 observations, 236 parameters).
