Procedure
A 20-g portion of 2,4-dichloroquinazoline was added to 200 ml of pyridine. The reaction mixture was stirred 11/2 hours, refluxed 11/2 hours, and then allowed to stir under a calcium sulfate drying tube for 3 days. The reaction mixture was filtered. The resulting solid rinsed well with pyridine, then ether, and was dried in vacuo giving 35.9 g of 1,1'-(2,4-quinazolinediyl)bis[pyridinium] dichloride (m.p. 150°-164° ).
