Procedure

A mixture of 0.194 g (0.500 mmol) 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, 0.180 mL (2.00 mmol) of methyl acrylate, 22.4 mg (0.0999 mmol) of palladium acetate, 122 mg (0.400 mmol) of tri-o-tolylphosphine and 0.278 mL, (2.00 mmol) of triethylamine in 4.0 ml of N,N-Dimethylformamide was heated at 100° C. for 6 hours. The mixture was concentrated in vacuum and partitioned between ethyl acetate and water. The organic extracts were washed with dilute aqueous HCl, water, brine, dried over Na2SO4 and concentrated in vacuum. The residue was purified on 4 g silica column eluting with heptane-ethyl acetate gradient to give (E)-methyl 3-(2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-9-yl)acrylate. Yield 0.11 g. M/z 394.2, calc. 393.18
