Ring Opening of 4-Chloroquinazoline into 2-Arylmethyleneaminobenzonitrile by Grignard Reaction
摘要:
The treatment of 4-chloroquinazoline (1) with arylmagnesium bromide (3) in tetrahydrofuran (THF) resulted in the formation of 2-arylmethyleneaminobenzonitrile (2). Continued reaction of ring opening of 1 and subsequent hydrolysis of the products (2) afforded the corresponding arenecarbaldehydes (4).
