	With triethylamine; In dichloromethane; at 20℃;Cooling;	Example 10 5-Chloro-N-[(3R)-1-cyano-3-pyrrolidinyl]-2-fluorobenzenesulfonamide To a chilled solution of <strong>[351003-49-1]5-chloro-2-fluorobenzenesulfonyl chloride</strong> (0.125 g, 0.546 mmol) and triethylamine (0.3 ml, 2.15 mmol) in DCM (2 mL) was added 1,1-dimethylethyl (3R)-3-amino-1-pyrrolidinecarboxylate (0.080 ml, 0.471 mmol). The reaction mixture was stirred at room temperature overnight. Water (1.5 ml) was added to the reaction mixture with stirring. The mixture was diluted with DCM (2 ml) and water (1.5 ml) and put through a phase separator to dry. Then 4N HCl in 1,4-dioxane (2.0 ml) was added. After 1.5 hours, the reaction was blown down to dryness. The dry material was then diluted with DCM (8 ml), and mixed with DIEA (0.45 mL, 2.58 mmol) and BrCN (0.40 mL, 1.2 mmol). The resultant mixture was stirred at room temperature overnight. The solvent was evaporated under vacuum and the solid purified by preparatory HPLC (without TFA) to afford the title compound (0.0671 g). LC-MS: m/z, 304 (M+H), rt 1.6 min.

Yield	Reaction Conditions	Operation in experiment
		General procedure: 2,3-Dichloro-N-[4-(6-chloro-5-cyano-pyrazin-2yl)-phenyl]-benzenesulfonamide (1.0 g) was suspended in a mixture of 5 ml iPrOH and 5 ml 35% hydrazine in water at RT and heated to 120C by microwave irradiation for 20 min under stirring in a sealed vessel. The reaction mixture was left to cool to RT. The precipitate was filtered off and washed with water to give the title compound as a yellow solid after drying under vacuum. The title compound was prepared in 22% yield according to the procedure described in example 1, employing 2,5-dichloro-benzenesulfonyl chloride instead of 2,3-dichloro-benzenesulfonyl chloride as starting material. The following modification was made. The crude reaction mixture was evaporated to dryness, redissolved in DMF and purified by preparative HPLC (C18 reversed phase column, elution with a water/MeCN gradient with 0.1 % TFA). The fractions containing the product were lyophilized to yield the title compound in the form of its salt with trifluoroacetic acid. The title compound was prepared by adapting the procedures described in example 1, employing 5-chloro-2-fluoro-benzenesulfonyl chloride instead of 2,3-dichloro-benzenesulfonyl chloride as starting material. The following modification was made. The crude reaction mixture was evaporated to dryness, redissolved in DMF and purified by preparative HPLC (C18 reversed phase column, elution with a water/MeCN gradient with 0.1 % TFA).

Yield	Reaction Conditions	Operation in experiment
	With pyridine; In dichloromethane; at 20℃; for 16h;	To a solution of 160 mg of tert-butyl 6-(4-aminophenyl)-3-(bis(tert- butoxycarbonyl)amino)-4-trifluoromethyl)-pyrazolo[3,4-d]pyrimidine-1 -carboxylate in 5 ml DCM and 43 muIota pyridine, 63 mg of 5-chloro-2-fluoro-benzenesulfonyl chloride were added. After stirring the reaction mixture for 16 h at RT, the solvents were removed under reduced pressure. The residue was dissolved in 10 ml DCM and 1 ml of TFA and stirred for 2 h at RT. Then toluene was added and the solvents were removed under reduced pressure to yield a brown solid. This crude product was purified by preparative HPLC (C18 reverse phase column, elution with a water/MeCN gradient with 0.1 % TFA). The fractions containing the product were lyophilized to yield the pure title compound in the form of its salt with trifluoroacetic acid. Yield: 23 mg. MS (ES+): m/e = 487.0 (M+H), chloro pattern.
