2-Methyl-4-phenyl-3,4-dihydro­quinazoline

The title compound, C(15)H(14)N(2), was formed during the lithia­tion of 2-methyl­quinazoline with phenyl­lithium followed by hydrolysis of the inter­mediate lithium 2-methyl-4-phenyl-4H-quinazolin-3-ide. NMR spectra as well as single-crystal X-ray structural data indicate that the reaction product to have the same structure in chloro­form solution as in the crystalline state. The phenyl substituent is twisted out of the plane of the 3,4-dihydro­quinazoline ring system by 86.47 (7)°. In the crystal, inter­molecular N—H⋯N inter­actions connect the mol­ecules into infinite chains.
