실험 절차

To a solution of 4-[2-(2-isopropyl-5-methoxymethyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (224 mg, 0.43 mmol) in IMS (3 mL) was added a catalytic amount of palladium on carbon (10% by wt) and the reaction mixture stirred under an atmosphere of hydrogen at 50° C. for 16 h. The reaction mixture was filtered and the solids washed with IMS (10 mL). The filtrate was concentrated in vacuo and the resultant residue subjected to flash chromatography (SiO2, eluting with 2% MeOH in DCM) to yield 4-[2-(2-Isopropyl-5-methoxymethyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-piperidine-1-carboxylic acid tert-butyl ester as a yellow oil (162 mg, 72%). LCMS: RT=5.05 min, [M+H]+=523
