Yield	Reaction Conditions	Operation in experiment
18%	With tris-(dibenzylideneacetone)dipalladium(0); potassium tert-butylate; 4,5-bis(diphenylphos4,5-bis(diphenylphosphino)-9,9-dimethylxanthenephino)-9,9-dimethylxanthene; In toluene; at 100℃; for 2h;Inert atmosphere; Sealed tube;	Method 1 : To a stirred solution of 6-aminoisoquinoline (18.3 g, 127.1 mmol) in toluene (400 mL) were added <strong>[66092-62-4]2-bromo-5-methyl-4-nitropyridine</strong> (23.0 g, 105.9 mmol), Xantphos (2.45 g, 4.24 mmol), Pd2(dba)3 (1.94 g, 2.12 mmol), tBuOK (16.6 g, 148.3 mmol) under nitrogen. Nitrogen was bubbled through the mixture for 5 min, and then the vial was sealed and heated at 100 C for 2 h. The mixture was filtered, and the filter cake washed with EtOAc until all product was extracted. Water was added to the filtrate and the org layer was separated, dried (MgS04), filtered and concentrated. The residue was taken up in water, triturated for 1 h, filtered, and dried in vacuo at 55 C. The resulting brown solid (dissolved in MeOH at pH 4) was purified via Prep HPLC (Stationary phase: RP XBridge Prep C18 OBD-IotaOmicronmuiotaeta, 50 x 150 mm, Mobile phase: 0.5% NH4OAc solution in water + 10% CH3CN, MeOH). The pure fractions were combined and the organic component of the eluent was evaporated. A red precipitate formed which was filtered, washed with water and dried. The resulting precipitate was stirred in DCM/MeOH/ 1 N NaOH (2 L/0.2 L/l L) until everything dissolved, and the org layer was separated. The aq. layer was extracted once more with DCM. The combined org layers were dried (MgS04), filtered and evaporated. The residue was triturated in a biphasic mixture of ether and water, filtered and dried in vacuo for 2 days at 50 C and 4 h in a lyophilizer at rt to give intermediate 2 as orange crystals (6.1 1 g, 18%).
