2-(2-Chloro-phen-yl)-2,3-dihydro-quinazolin-4(1H)-one.

The title compound, C(14)H(11)ClN(2)O, was synthesized by the reaction of 2-chloro-benzaldehyde and 2-amino-benzamide in an ionic liquid. The pyrimidine ring adopts a skew-boat conformation and the two benzene rings make a dihedral angle of 87.1 (1)°.

[Detecting the haplotype of three Y-STR loci by fluorescent multiplex amplification].

Objective: To establish a fluorescent multiplex PCR system for typing Y-STR loci Y-GATA-A7.1, DYS456 and DYS443, and investigate their haplotype frequencies in Chinese Han population.

Methods: 203 unrelated males of Han population living in Zhengzhou were typed by fluorescent multiplex amplification system and ABI 3100 genetic analyzer.
