实验步骤: To a suspension of 7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxylic acid (0.6 g, 2.1 mmol) in tetrahydrofuran (10 ml) were added oxalyl chloride (0.33 ml, 4.3 mmol) and N,N-dimethylformamide (1 drop) at 0° C., and the mixture was stirred at room temperature for 2.5 hours. The solvent was evaporated, and the residue was dissolved in tetrahydrofuran (6 ml). To the mixture was dropwise added 4-(t-butyldimethylsilyloxymethyl)aniline (0.56 g, 2.4 mmol) and triethylamine (0.36 ml, 2.6 mmol) in tetrahydrofuran (2 ml) at 0° C., and the mixture was stirred at room temperature for 16 hours.
