Stage #1: 2-bromo-5-methyl-5H-pyrrolo[2,3-b]pyrazine With n-butyllithium In hexane; toluene at -78℃; for 1.5h; Stage #2: With zinc(II) chloride In tetrahydrofuran; 2-methyltetrahydrofuran; hexane; toluene at -78 - 20℃; for 3h; Stage #3: ethyl (S)-2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-(tert-butoxy)acetate With tetrakis(triphenylphosphine) palladium(0) In tetrahydrofuran; 2-methyltetrahydrofuran; hexane; toluene at 60℃; for 3h; Inert atmosphere; 19 Preparation of ethyl (S)-2-(tert-butoxy)-2-(7-(4-chlorophenyl)-5-methyl-2-(5-methyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)benzo[d]thiazol-6-yl)acetate To an oven-dried round bottom flask was charged 2-bromo-5-methyl-5H-pyrrolo[2,3-b]pyrazine (896 mg, 4.23 mmol, 2.00 equiv), which was then dissolved in 3:1 toluene:hexanes (12 mL). The reaction solution was then cooled to -78° C. and a solution of n-butyllithium in hexanes (2.50 M, 1.86 mL, 4.65 mmol, 2.20 equiv) was added dropwise. After stirring for 1.5 h, a solution of zinc chloride in 2-methyltetrahydrofuran (1.90 M, 2.56 mL, 4.86 mmol, 2.30 equiv) was then added, followed by 10 mL of tetrahydrofuran. After stirring at -78° C. for 25 min, the reaction mixture was warmed to 0° C. and stirred for an additional 35 min. The reaction was then allowed to warm to room temperature and was stirred for an additional 2 h. Ethyl (S)-2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-(tert-butoxy)acetate (1.05 g, 2.11 mmol, 1.00 equiv) and Pd(PPh3)4(244 mg, 0.211 mmol, 0.10 equiv) were then added. The reaction mixture was sparged with argon for 10 min and subsequently heated to 60° C. After stirring for 3 h, the reaction was cooled to room temperature. 1 M hydrochloric acid was added until all solids dissolved. Saturated aqueous NaHCO3 was added until pH˜7 was reached. The reaction was then diluted with EtOAc (30 mL) and the organic and aqueous layers were separated. The aqueous layer was extracted with additional EtOAc (3*15 mL) and the organic layers were all combined, washed with brine (30 mL), dried over anhydrous MgSO4, filtered, and concentrated. The crude product was purified via CombiFlash (Peeke Scientific, silica gel, gradient: 0-100% EtOAc/hex) to afford the desired product as a pale yellow flocculent solid. LCMS-ESI+: calc'd for C29H30ClN4O3S: 549.17 [M+H]+; found: 549.19.

55% With tris-(dibenzylideneacetone)dipalladium(0); caesium carbonate; 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene In 1,4-dioxane at 90℃; for 40h; Inert atmosphere; BO /V-{5-Methyl-5H-pyrrolo[2,3-b]pyrazin-2-yl}-/V-({5-[5-(trifluoromethyl)-1,2,4- oxadiazol-3-yl]thiophen-2-yl}methyl)pyrazin-2-amine Under Ar(g), to a mixture of pyrazin-2-amine (1) (123mg, 1.3mmol), N- methyl-5-bromo-4,7-diazaindole (2) (250mg, 1.2mmol), Cs2C03 (0.77g, (0493) 2.4mmol) was added degassed dry 1 ,4-dioxane (13mL). The reaction mixture was then flushed with Ar(g) for 1 min before Pd2(dba)3 (54mg, 0.06mmol) and Xantphos (75mg, 0.13mmol) were added. The reaction mixture was heated up to 90°C for 40h. It was then cooled down to rt and concentrated in vacuo, CH2CI2 (15mL) and H20 (15mL) were added. The organic phase was separated and the water layer was extracted with CH2CI2 (15mL). The organic layers were combined and Pd-scavenger (MP-TMT, ~400mg, 1.3mmol/g) was added. This was shaken for several hours followed by filtration. The filtrate was concentrated in vacuo, dissolved in DMSO (4mL) and purified by basic prep LCMS to yield (3) as a solid (147mg, 55%). (0494) LCMS (ES): Found 227.2 [M+Hf.
