Yield	Reaction Conditions	Operation in experiment
49%	With hydrogen bromide; bromine In water at 100℃; for 9 h;	To a flask equipped with a reflux device, 25.0 g (183.7 mmol) of the compound (a), and 150 mL of 48percent hydrobromic acid were added. After heating to 100° C., 8.5 mL (165.4 mmol) of bromine was dropped, the resultant was stirred at 100° C. for nine hours, and then it was let cool. After a reaction was finished, 200 mL of dichloromethane was added, precipitated solid was dissolved, and further 100 mL of an aqueous sodium sulfate solution was added. An organic layer was collected, washed with a saturated aqueous sodium hydrogen carbonate solution, dried with anhydrous sodium sulfate, and then a solvent was removed under reduced pressure to obtain an unrefined compound (b). The compound (b) was suspended in 200 mL of hexane/ethyl acetate (4:1, volume ratio), remaining solids were filtered to thereby remove 4,7-dibromo-2,1,3-benzothiadiazole being a by-product. The filtrate was condensed again, suspended in 200 mL of hexane, and remaining solids were filtered, to thereby obtain 11.2 g of the compound (b). Further, the filtrate was condensed, and refinement was performed by a column chromatography method using hexane/ethyl acetate (97:3, volume ratio) as a developing solution, to thereby obtain 8.0 g of the compound (b). A sum total was 19.2 g (89.3 mmol), and a yield was 49percent.

Yield	Reaction Conditions	Operation in experiment
92%	With sodium tetrahydroborate In ethanol at 20℃; for 16 h;	2000mL 1-neck flask (one neck flask) for 4-bromo-benzo [c] [1,2,5] thiadiazole (10g, 46.5 mmol), NaBH4 (17.6g, 465 mmol) were placed into a 900mL EtOH after stirring at room temperature for 16 hours. When the reaction is complete, remove the solvents by rotary evaporation the drier and extracted with CHCl3. Thus extracted organic layer was washed with brine solution. Thereafter, the dried organic layer was again put on MgSO4 and the solvent removed by evaporation dryer to give the title compound C-2-1 (8.0g, 47.6 mmol, 92percent).
81%	Stage #1: With sodium tetrahydroborate; cobalt(II) chloride hexahydrate In methanol for 3 h; Reflux	Example 8: N,N-dimethyl-3-(3-(2-oxo-2,3-dihydro-1 H-benzo[d]imidazol-4-yl)-2- (pyridin-4-yl)pyrazolo[1 ,5-a]pyrimidin-7-yl)benzene-sulfonamide <n="33"/> Step 1 : 3-Bromo-benzene-1 ,2-diamine To a solution of 4-bromo-benzo[1 ,2,5]thiadiazole (1.15g, 5.35 mmol) in methanol (10 ml_) was added sodium borohydride (203 mg, 5.35 mmol) and cobalt chloride hexahydrate (120 mg, 0.533 mmol). The mixture was refluxed for 3 hours, cooled to room temperature and then filtered to remove the black solid. The solvent was evaporated, water (100 ml_) was added and the product was extracted with Et₂O (3 x, 30 mL). The combined organic extracts were dried over Na₂Sψ₄ and the solvent removed, resulting in the air-unstable 3-bromo-benzene-1 ,2- diamine (810 mg, 81percent yield). MS: 187.0 [M+H].
81%	With sodium tetrahydroborate; cobalt(II) chloride hexahydrate In methanol for 3 h; Reflux	Example 83: Ethyl 3-[3-(2-oxo-2,3-dihydro-1 H-benzimidazol-4-yl)-2-pyridin-4- ylpyrazolo[1 ,5-a]pyrimidin-7-yl]-8-azabicyclo[3.2.1]octane-8-carboxylate; <n="98"/> Step 1 : To a solution of 4-bromo-benzo[1 ,2,5]thiadiazole (1.15g, 5.35 mmol) in methanol (10 ml.) was added sodium borohydride (203 mg, 5.35 mmol) and cobalt(ll) chloride hexahydrate (120 mg, 0.533 mmol). The mixture was refluxed for 3 hours, then cooled to room temperature and filtered to remove the black solid. The solvent was evaporated, water (100 ml.) was added and the mixture was extracted with ether (3 x 30 ml_). The combined organic extracts were dried over sodium sulfate, filtered, and then concentrated in-vacuo, to provide 3-bromo-benzene-1 ,2-diamine (810 mg, 81 percent yield). MS: 187.0 [M+H].
