Reaction Steps

To a stirred mixture of NaH (200 mg, 60% in mineral oil, 5.0 mmol, Aldrich) in 10 mL of DMF at RT was added 6-hydroxy-naphthalene-2-carboxylic acid methyl ester (Step a, 675 mg, 3.34 mmol). After 20 min, 4-chloro-6,7-dimethoxy-quinazoline (750 mg, 3.34 mmol, Oakwood) was added and the reaction was heated to 60° C. for 20 min. The reaction was cooled to RT, quenched with saturated aqueous NH4Cl solution (30 mL) and extracted with CHCl3 (30 mL). The organic solution was washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by column chromatography (30% EtOAc/hexane) to give the title compound as a white solid. MS (ESI, pos. ion) m/z: 390.9 (M+1). Mass Calc'd for C22H18N2O5: 390.12.
