Abstract

6-Bromo-2-phenyl-4H-3,l-benzoxazinone (7) reacted with methylmagnesium iodide to give 2-benzoylamino-5- bromophenyldimethylcarbinol (8) in 54% purified yield. Similarly, 3-anilino-6-bromo-2-phenyl-4(3H)-quinazolinone (9) afforded the corresponding dimethylcarbinol 10 in 65% yield after crystallization on its reaction with methylmagnesium iodide. However, reaction of methylmagnesium iodide with 6-bromo-3-(4-chloro-phenylidene)-2-phenyl- 4(3H)-quinazolinone (11) gave 6-bromo-3-[l-(4-chlorophenyl) ethylamino]-4(3H)-quinazolinone (12) in 48% yield after purification.
