실험 절차

To a solution of 2-iodo-1-methyl-4-(1-methylpiperidin-4-yloxy)-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulene (example 133) (110 mg, 0.251 mmole) in DMF (4 mL) are added potassium 4-tributylstannylpyridine (354 mg, 1 mmole), Pd(PPh3)4 (28 mg, 0.025 mmole), LiCl (50 mg, 1.25 mmole). The flask is evacuated and filled with argon. The reaction mixture is heated at 110° C. for 5 hours. AcOEt and water are added, as well as a 10% KF solution. The aqueous phase is extracted with AcOEt. The organic phase is washed with 0.5N HCl. The HCl phase is made alkaline with 1H NaOH and the aqueous phase is extracted with AcOEt. The organic phase is dried over MgSO4, filtered and the solvent removed under reduced pressure. The residue is purified by silica gel chromatography eluting with (CH2Cl2:MeOH) (98:2) then (CH2Cl2:MeOH:NH4OH) (95:5:0.5). The residue is the re-purified to afford by silica gel chromatography eluting with (toluene:acetone:NEt3) (10:90:2) to (5:95:5) to give 1-methyl-4-(1-methylpiperidin-4-yloxy)-2-pyridin-4-yl-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulene.
