In a round bottomed flask, sodium hydride (121 mg, 3.14 mmol), a 60% dispersion in mineral oil, was suspended in 20 mL of dry THF. To this suspension 3-aminothiophenol (394 mg, 3.14 mmol) was added and the reaction stirred for 30 minutes. To this solution 4-chloro-6-(3-chloropropoxy)-7-methoxyquinazoline (900 mg, 3.14 mmol) and the reaction stirred overnight. The reaction was quenched with water, concentrated, and partitioned between water and ethyl acetate. After extracting twice, the extracts were combined, dried over magnesium sulfate, filtered and concentrated to give 3-(6-(3-chloropropoxy)-7-methoxyquinazolin-4-ylthio)aniline as a yellow solid and used without further purification. 1H(DMSO-d6) 8.70 (s, 1H), 7.34 (s, 1H), 7.15 (m, 1H), 6.80 (s, 1H), 6.75 (m, 2H), 4.28 (m, 2H), 3.99 (s, 3H), 3.84 (m, 2H), 2.38 (m, 2H); LCMS (ESI) m/z 376 (M+H).
