摘要:
The preparation of 6-aminoquinazolin-4(3H)-ones requires the use of platinum metal group catalysis on the corresponding C-6-iodo or 6-bromo precursors. Herein, we report to our knowledge the first successful SNAr reaction directly at the unactivated C-6 position of the quinazolin-4(3H)-one nucleus. (C) 2011 Elsevier Ltd. All rights reserved.
