4-(Dimethylamino)Benzaldehyde → HCID 23323163, compound

Participants

Reaction Steps

2-(4'-chlorophenyl)-3-phenyl-1,2,3,4-tetrahydroquinazoline was prepared by the method of Example 1 but substituting 4-chlorobenzaldehyde for the 4-dimethylaminobenzaldehyde used in Example 1. The crude product had a melting point of 177° C. 0.5 g (0.0015 mol)of this compound and 0.18 g (0.005 mol) p-anisidine were fused together at 120 to 140° C. for about 1 hr. The product was the title compound as a white solid having a melting point of 116° C. This compound was imaged on CF paper, as described above, and gave an intense yellow coloration. The UV-visible spectrum of the coloured form of this compound showed peaks at 416 nm and 349 nm (relative intensity 0.98).
