Participants

Reaction Steps

6-(3-methoxyphenyl)-2-(pyridine-3-yl)quinazoline-4-ol was prepared from 6-bromo-2-(pyridin-3-yl)quinazolin-4-ol (synthesized following Scheme 70 substituting 2-amino-5-bromobenzamide for 2-amino-5-bromo-3-methylbenzamide) and 3-methoxylphenylboronic acid as described in Scheme 72 using method AQ2. The resultant product, 6-(6-methoxypyridin-3-yl)-N-methyl-2-(pyridine-3-yl)quinazoline-4-amine, was a pale yellow solid (19.1 mg, 51%). LCMS m/z=344 (M+1) (Method C) (retention time=2.01 min). 1H NMR (300 MHz, DMSO) δ 9.64 (d, J=1.3 Hz, 1H), 8.84-8.74 (m, 1H), 8.68 (dd, J=6.2, 1.7 Hz, 2H), 8.57 (d, J=1.6 Hz, 2H), 8.16 (ddd, J=14.4, 8.7, 2.2 Hz, 2H), 7.85 (d, J=8.7 Hz, 1H), 7.54 (dd, J=7.9, 4.8 Hz, 1H), 7.00 (d, J=8.7 Hz, 1H), 3.93 (s, 3H), 3.18 (d, J=4.3 Hz, 3H).
