81% at 40℃; for 0.5h;Microwave irradiation; B. 6-Bromo-1,4-diethyl-7-methyl-1,4-dihydro-quinoxaline-2,3-dione (Compound 24B); Compound 24A (160 mg) in 1 mL of diethyl oxalate was heated in microwave at 140 C. for 30 min. Reaction was then cooled to rt, diluted with hexanes and resulting dark brown solid (164 mg, 81%) was collected by filtration. Solution of above intermediate (164 mg, 1 eq.) and ethyl iodide (0.52 mL, 10 eq.) in 3 mL of anhydrous DMSO was cooled on ice and crushed into powder KOH (144 mg, 4.0 eq.) was added slowly. Reaction was stirred on ice for 1 hour and at rt for another hour. Reaction was then partitioned between CH2Cl2 and water. The organic layer was separated, dried over Na2SO4, filtered and the solvent was removed in vacuo. Crude was purified by column chromatography (40:60 hexane/EtOAc) to obtain 157 mg (78 %) of product. MS (electrospray): mass calculated for C13H15BrN2O2, 311.17; m/z found 312.2, [M+H]+.

The reaction was allowed to stir for 2.5 hours. Reaction was then diluted with 15 mL of water and Zn dust (1.29 g, 3 eq.) was added. Reaction was stirred for 1 hour, filtered and then pH was adjusted to 7 with ammonia. The aqueous layer was extracted with CH2Cl2 twice, dried over Na2SO4, concentrated and adsorbed on silica. Purification by flash column chromatography (60:40 hexanes/EtOAc) afforded 1.1 g (83 %) of product as off-white solid. MS (electrospray): mass calculated for C7H9BrN2, 201.06; m/z found 202.2, [M+H]+.

YieldReaction ConditionsOperation in experiment
77% In water; acetonitrile; at 0 - 20℃; Step A6-bromo-5-m zol-2-[00228] A cooled 0 C solution of 4-bromo-5-methylbenzene-1 ,2-diamine (0.86 g, 4.28 mmol) in acetonitrile (4 mL) and water (2 mL) was treated with cyanogen bromine (0.498 g, 4.70 mmol). The reaction mixture was allowed to warm slowly to room temperature and stir overnight. The reaction mixture was partitioned between DCM (100 mL) a sat. NaHCC^ solution (100 mL) and water (20 mL). The organic layer was dried with Na2SC>4, filtered and concentrated to obtain a brown solid. 67-1 The aqueous layer was filtered to yield a light tan solid. The is^SC^ contained a tan solid as well. The salts were dissolved in water, sonicated then filtered to yield a pink solid. Spectra of the pink solid and the material from the aqueous filtration were comparable so the samples were combined to yield 6-bromo-5-methyl-1 H- benzo[d]imidazol-2-amine as a light tan solid (825 mg, 3.28 mmol, 77 % yield). 1H NMR (400 MHz, DMSO-d6) delta ppm 10.83 (br. s., 1 H) 7.21 - 7.40 (m, 1 H) 7.02 - 7.16 (m, 1 H) 6.67 (br. s., 2 H) 2.24 - 2.39 (m, 3 H).
