Yield	Reaction Conditions	Operation in experiment
	In acetic acid;	EXAMPLE 2 Production of the hydroxyphenyltetrahydrophthalimide (II) <strong>[84478-72-8]2-Chloro-4-fluoro-5-aminophenol</strong> (6.6 g) and 3,4,5,6-tetrahydrophthalic anhydride (6 g) were dissolved in acetic acid (20 ml) and refluxed for 2 hours. The resultant mixture was allowed to cool to room temperature and poured into ice-water, followed by extraction with ether. The ether extract was washed with a saturated sodium hydrogen carbonate solution and water in order, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by silica gel chromatography to give 4.0 g of N-(4-chloro-2-fluoro-5-hydroxyphenyl)-3,4,5,6-tetrahydrophthalimide. M.P., 151 C.

The resulting mixture was cooled to -30 to -25 C., and a solution of anhydrous stannous chloride (20.5 g) in conc. hydrochloric acid (40 ml) was added thereto, followed by stirring at -10 to 0 C. for 3 hours. The precipitated crystals were collected by filtration, washed with a small amount of water and dissolved in a 10% aqueous sodium hydroxide solution. The resultant solution was adjusted to pH 7 and extracted with ethyl acetate. The extract was dried and concentrated. The crystallized residue was washed with ether to obtain 1 g of 4-chloro-2-fluoro-5-hydroxyphenylhydrazine. m.p., 149-150 C. (decomp.).

		PRODUCTION EXAMPLE 36 (Production of Compound 1-39 1) First, 32.3 g of <strong>[84478-72-8]5-amino-2-chloro-4-fluorophenol</strong> was mixed with 150 ml of concentrated hydrochloric acid, and the mixture was stirred at 50 C. for 30 minutes, to which a solution of 15 g of sodium nitrite dissolved in 40 ml of water was added dropwise at 0 C. over 10 minutes.. After stirring at 0 C. for 1 hour, the mixture was cooled to -50 C. Then, a solution of 132 g of tin (II) chloride dissolved in 132 g of concentrated sulfuric acid was rapidly added dropwise at -50 C., and the mixture was gradually warmed to room temperature and stirred for 1 hour.. The solids formed were collected by filtration and dried at 80 C. under reduced pressure to give 75 g of the crude 2-fluoro-4-chloro-5-hydroxyphenylhydrazine hydrochloride crystals. 1H-NMR (DMSO-d6, TMS delta (ppm)) 3-5 (2H, br), 6.73 (1H, d), 7.22 (1H, d), 8.20 (1H, s), 9-11 (2H, br)

Yield	Reaction Conditions	Operation in experiment
	In (+/-)-2-pentanol; N,N-dimethyl-formamide;	EXAMPLE 12 A solution of 4-chloro-6-methoxy-7-(3-morpholinopropoxy)cinnoline hydrochloride (83 mg, 0.2 mmol) and <strong>[84478-72-8]4-chloro-2-fluoro-5-hydroxyaniline</strong> (42 mg, 0.26 mmol), (prepared as described in EP 061741 A2), in 2-pentanol (5 ml) containing DMF (0.5 ml) was heated at 120 C. for 2.5 hours. The work up procedure was identical to the synthesis of the final productproduct in Example 11 and gave 4-(4-chloro-2-fluoro-5-hydroxyanilino)-6-methoxy-7-(3-morpholinopropoxy)cinnoline as the hydrochloride salt (70 mg 65%). m.p. 218-225 C.; 1H NMR Spectrum: (DMSOd6; CD3COOD) 2.4 (m, 2H); 3.35 (m, 6H); 3.9 (m, 4H); 4.1 (s, 3H); 4.4 (t, 2H); 7.2 (d, 1H); 7.45 (s, 1H); 7.6 (d, 1H); 8.1 (s, 1H); 8.35 (s, 1H); MS-ESI: 463 [MH]+;
