실험 절차

In a 2-liter flask were charged 38.2 g (0.378 mol) of diisopropylamine and 265 ml of tetrahydrofuran (THF). The mixture was cooled to 0° C. and 229 ml of a hexane solution of 1.65 M n-butyllithium was added thereto. After 15 minutes' stirring, the mixture turned dark brown. The solution was further cooled to -78° C., to which was added 50 ml of a THF solution of 50 g (378 mmol) of 1-indanone and the resulting mixture was stirred for 30 minutes. Then, 205 g (1.89 mol) of trimethylsilyl chloride was added at -78° C., and the coolant was removed to raise the temperature to room temperature followed by stirring for 2 hours.
