6-Benzyloxy-4-chloro-7-methoxy-3-nitroquinoline (6.75 g, 19.58 mmol) and 4-amino-3-fluorobenzonitrile (2.46 g, 18.1 mmol) were dissolved in glacial acetic acid (106 ml) and stirred at 50° C. for 18 h overnight. The suspension obtained was subsequently added to water (1 l) and stirred for a further 30 min. The precipitate formed was filtered off with suction, rinsed with water and dried in vacuo, giving 4-(6-benzyloxy-7-methoxy-3-nitro-quinolin-4-ylamino)-3-fluorobenzonitrile (6.69 g, 15.06 mmol) as solid. MS: 445.1 (M+H+), TLC (HPTLC): Rf=0.31 (cyclohexane/ethyl acetate 2:1, parts by volume).
