実験手順

2.500 g of methyl 2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepine-9-carboxylate are dissolved under argon in 30 ml of N,N-dimethylformamide and the solution is cooled to 0° C. in an ice bath. 0.600 g of sodium hydride dispersion (60%) is added in portions and the reaction mixture is subsequently stirred at 0° C. over a further 1 hour. 0.502 ml of 2-(trimethylsilyl)ethoxymethyl chloride is added and the reaction mixture is subsequently stirred at room temperature over 11 hours. The reaction mixture is poured onto 150 ml of saturated aqueous sodium hydrogencarbonate solution and extracted with 2×150 ml of tert-butyl methyl ether. The combined organic phases are dried over sodium sulphate and concentrated by evaporation. The title compound is obtained as a reddish oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.35 (1:1 EtOAc-heptane); Rt=5.02.
