실험 절차
The bromide 20 available from references 9 and 10 was reacted with trimethylsilyacetylene in the presence of a palladium catalyst to provide trimethylsilyl analog 52. This product was methylated with methyl iodide/sodium hydride to give the N-methyl benzodiazepine 54 (XLi 351). This was subjected to fluoride-mediated desilation to furnish 53 (XLi 350) and 55 (XLi 352).
