Reaction Steps

A microwave vial was charged with a solution of 9-bromo-2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine 411 (0.300 mg, 0.699 mmol) in 2.0 ml DMF. To this solution was added zinc cyanide (250 mg, 2.1 mmol). The reaction mixture was degassed by bubbling nitrogen through the stirred mixture via a syringe. After several minutes the syringe was removed and Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (100 mg, 0.140 mmol) was added and the reaction vial was quickly sealed. The sealed vial was flash heated in a microwave at 125° C. for 30 minutes. The cooled reaction was diluted with EtOAc and the organic solution was washed with water ×1, saline ×1 and dried (Na2SO4) before concentration in vacuo. The crude residue was purified by preparative RP-HPLC to give 156 mg of 443 (59% theoretical yield) 1H NMR (400 MHz, DMSO) δ 8.55 (d, J=8.2 Hz, 1H), 8.02 (s, 1H), 7.74-7.46 (m, 2H), 5.79 (dt, J=13.1, 6.6 Hz, 1H), 4.57 (s, 4H), 2.29 (d, J=28.5 Hz, 3H), 1.46 (d, J=6.6 Hz, 6H)
