A study concerning the synthesis, basicity and hydrolysis of 4-amino-2-(n,n-diethylamino)quinazoline derivatives
Zielinski, Wojciech,Kudelko, Agnieszka
, p. 1289 - 1292 (2002)
A group of 2-(N,N-diethylamino)-4-aminoquinazoline derivatives have been synthesized in the reaction of N1,N1-diethyl-N2-arylchlorocarboxyamidines with cyanamide in the presence of TiCl4 as a catalyst. Such quin
