Abstract

C₂₅H₂₁N₃, M_r = 363.46, monoclinic, P2₁/n, a = 9.245 (2), b = 23.502 (5), c = 9.340 (2) Å, β= 103.50(3)°, V=1973.3(2) ų, Z=4, D_x= 1.220 (2) g cm^-3, λ (Mo Kα )= 0.71069 Å, μ = 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.
