| Product | (7-Bromo-quinazolin-4-yl)-(5-trifluoromethyl-pyridin-2-yl)-amine | HCID 11485491 | — |
Reaction Steps
Heat a mixture of 7-bromo-4-chloro-quinazoline (200 mg, 0.821 mmol) and 2-amino-5-trifluoromethyl-pyridine (239 mg, 1.48 mmol) at 230° C. for 2 minutes. Cool and partition the solid residue between EtOAc and 10% NaOH. Dry the EtOAc layer (Na2SO4), remove the solvent under reduced pressure, and purify via flash chromatography to yield (7-bromo-quinazolin-4-yl)-(5-trifluoromethyl-pyridin-2-yl)-amine as a yellow solid.
