C25H21N3, M(r) = 363.46, monoclinic, P2(1)/n, a = 9.245 (2), b = 23.502 (5), c = 9.340 (2) angstrom, beta = 103.50 (3)degrees, V = 1973.3 (2) angstrom3, Z = 4, D(x) = 1.220 (2) g cm-3, lambda(Mo Kalpha) = 0.71069 angstrom, mu = 0.068 cm-1, F(000) = 768, T = 292 K, R = 0.091 for 1442 unique observed reflections. The dihydropyrimidine ring adopts a distorted sofa conformation. The aryl substituents on the saturated C atoms have an axial orientation.
