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) (50 mg, 0.114 mmoles) in THF (0.7 mL) in a screw-capped vial under argon are added a 1M aqueous solution of K2CO3 (0.5 mL, 0.5 mmole), PdCl2(dppf)2 (4.5 mg, 6 μmole) and 4-(trans-4-hydroxycyclohexylcarbamoyl)phenylboronic acid (45 mg, 0.150 mmole). The reaction mixture is heated at 95° C. overnight. Water is added to the reaction mixture and the aqueous phase is extracted three times with CH2Cl2. The organic phase is dried over magnesium sulphate, filtered and the solvent is removed under reduced pressure. The residue is pre-purified by silica gel chromatography using (CH2Cl2:MeOH:NH4OH) with a gradient from (98:2:0.2) to (96.5:3.5:0.35). The residue is purified by preparative TLC over silica gel using (CH2Cl2:MeOH:NH4OH) with a gradient from (9:1:1) to afford N-(4-hydroxycyclohexyl)-4-[1-methyl-4-(1-methylpiperidin-4-yloxy)-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulen-2-yl]benzamide.
