Reaction Steps
To a solution of 2-(4-chloro-7-methylquinazolin-2-yl)phenol (200 mg, 0.74 mmol) in 10 mL DMF was added (S)-1-benzyl-3-isopropylpiperazine followed by the addition of triethylamine (206 μL). The reaction was heated at 85° C. for two hours. The reaction was quenched with water after cooling it to room temperature. The aqueous layer was extracted twice with CH2Cl2, and the combined extracts were dried over MgSO4, filtered, and concentrated. The reaction was purified via silica gel chromatography using 1:1 hexanes:CH2Cl2 solvent system to yield 2-(4-((S)-4-benzyl-2-isopropylpiperazin-1-yl)-7-methylquinazolin-2-yl)phenol (230 mg, 64%). LC/MS: m/z 453.5 (M+H)+ at 2.61 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
