실험 절차

To a solution of 10 g of 2-hydroxy-6,11-dihydrodibenz[b,e]oxepin-11-one in 50 ml of dimethylformamide are added 6.5 g of imidazole and 7 g of t-butyldimethylchlorosilane and the mixture is stirred for 1 hour. After adding 300 ml of toluene, successively washing with water and a saturated saline solution and drying over magnesium sulfate, the solvent is distilled off under reduced pressure to give 13 g of 2-(dimethyl-t-butylsilyloxy)-6,11-dihydrodibenz[b,e]oxepin-11-one (oil). Mass spectrum m/z: 340(M+).
