Yield	Reaction Conditions	Operation in experiment
46%	With hydrogenchloride; tin; for 1.5h;Reflux;	Concentrated hydrochloric acid (10 mL) was slowly added dropwise to a mixture of difluoronitroaniline 7 (1.6 g, 9 mmol) and tin (22.5mmol). The reaction mixture was heated at reflux for 1.5 h, cooled tor.t., and neutralized with 50% NaOH solution to pH 9-10. The precipitate was filtered, dried, and extracted with hot EtOAc (80 mL). Afterevaporation of the filtrate, diamine 9 was obtained.Yield: 0.60 g (46%); brown crystals; mp 55-57 C; Rf 0.86.
	palladium;	a) 1,2-Diamino-3,5-difluorobenzene was obtained by hydrogenation of 5 g of 2-amino-3,5-difluoronitrobenzene with 0.8 g of palladium catalyst on carbon at RT and normal pressure. After distilling off the solvent, a dark partially crystalline oil was obtained, which was used without further purification for the preparation of stage b.
	With hydrogen;palladium 10% on activated carbon; In ethanol; at 20℃; for 2h;	Preparation of (S)-(2-(3,5-dichlorobenzyl)pyrrolidin-1-yl)(5,7-difluoro-3-hydroxyquinoxalin-2-yl)methanone (9-16); Step 1: 10% Pd/C (100 mg) was added a solution in compound 9-11 (500 mg, 2.87 mmol) in EtOH (50 mL). The resulting suspension was stirred under a H2 balloon at room temperature for 2 h. The mixture was filtered through Celite and the filtrate was concentrated in vacuo to give desired product 9-12.
