摘要
The title compound 2-amino-4-chloro-5-（4-methylbenzyl）-6-methylpyrimidine （C26H28Cl2N6, Mr = 495.44） has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction analysis. The crystal belongs to monoclinic, space group P21/c with a = 14.892（7）, b = 6.129（3）, c = 14.889（7）A, β = 109.795（8）°, V = 1278.7（10）A^ 3, Z = 2, F（000） = 520, Dc = 1.287 g/cm^3, μ = 0.280 mm^-1, the final R = 0.0577 and wR = 0.1589 for 1357 observed reflections with I 〉 2σ（I）. A total of 6091 reflections were collected, of which 2257 were independent （Rint = 0.033）. The X-ray analysis reveals that the chlorine atom and methyl of the title compound are disordered.
