Synthesis of 11H-pyrido[2,1-b]quinazolin-11-one and derivatives using ultrasound irradiation
Docampo Palacios, Maite L.,Pellon Comdom, Rolando F.
, p. 1777 - 1781 (2003)
An improved synthesis of 11H-pyrido[2,1-b]quinazolin-11-one and derivatives, by the condensation of 2-chlorobenzoic acid and 2-aminopyridine derivatives in N,N-dimethylformamide (DMF) is reported using ultrasound irradiation. The derivatives were prepared
Microwave-promoted Ullmann condensation of 2-aminopyridines with 2-chlorobenzoic acids

, p. 1715 - 1719 (2006)
A new efficient synthetic method of microwave-promoted Ullmann condensation of 2-aminopyridines with 2-chlorobenzoic acids to yield various substituted 11H-pyrido[2,1-b]quinazolin-11-ones in dry media is presented. Results were compared with those obtaine
Synthesis of 9-methyl-11H-pyrido[2,1-b] quinazolin-11-one using the Ullmann condensation
Pellon, Rolando F.,Docampo, Maite L.,Kunakbaeva, Zulfia,Gomez, Victoria,Velez-Castro, Herman
, p. 481 - 485 (2006)
The Ullmann condensation between 2-chlorobenzoic acid and 2-amino-6-methyl pyridine in DMF as solvent yielded 2-[(6-methyl-2-pyridinyl)amino] benzoic acid. The cyclization of this acid gave two isomers, the 9-methyl-11H-pyrido[2,1-b] quinazolin-11-one and
Synthesis of 11H-pyrido[2,1-b]quinazolin-11-one and derivatives
Pellon, Rolando F.,Carrasco, Ramon,Rodes, Lorenzo
, p. 3869 - 3876 (1996)
The synthesis of 11H-pyrido[2,1-b]quinazolin-11-one (IV) and derivatives, by the condensation of o-chlorobenzoic acid and 2-aminopyridine in DMF is reported.
