실험 절차

A mixture of 10-chloro-2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydroimidazo[1,2-d]pyrido[4,3-f][1,4]oxazepine (132 mg, 0.400 mmol), 1-methyl-piperazine (88.7 uL, 0.800 mmol), palladium acetate (44.9 mg, 0.200 mmol), 2,8,9-tri-1-butyl-2,5,8,9-tetraaza-1-phosphabicyclo[3.3.3]undecane (71.0 uL, 0.200 mmol) and Sodium tert-butoxide (38.4 mg, 0.400 mmol) in 1,4-Dioxane (8.0 mL) was degassed. The reaction was microwaved on 200 watts, 120° C. for 30 minutes. The mixture was filtered and the filtrate concentrated in vacuum. The residue was partitioned between water and ethyl acetate. The organic extracts were washed with water, brine and dried over MgSO4 and concentrated in vacuum. The residue was purified on 4 g silica column using 5-10% gradient of methanol containing 1% of ammonia in DCM to give 234. Yield 50 mg (30%). MS: 395.2. 1H NMR (500 MHz, DMSO) δ 8.04 (s, 1H), 8.03 (s, 1H), 7.94 (s, 1H), 7.63 (s, 1H), 5.69 (dt, J=13.3, 6.6, 1H), 4.61-4.53 (m, 2H), 4.49-4.41 (m, 2H), 3.41 (s, 4H), 2.45 (s, 4H), 2.23 (s, 3H), 1.50 (d, J=6.6, 6H).
