Phenylboronic Acid → 2,4-Dichloro-6-phenylpyrimidine

참여 물질

반응 단계

As shown in Scheme 17, reaction of 2,4,6-trichloropyrimidine (8) with phenylboronic acid occurred at position 6 of the pyrimidine ring to give 2,4-dichloro-6-phenylpyrimidine (39) as the only isolated product. This is in contrast to the amine displacement reactions of Schemes 3 and 16, which occurred largely at the 4 position. Subsequent reaction with bridged C5-C9heterobicycle compound 2 occurred as expected at position 4.
