Reaction Steps
A solution of EXAMPLE 4A (23.43 g, 100.0 mmol), 2-bromobenzyl bromide (26.24 g, 105.0 mmol) and diisopropylethylamine (20.94 mL, 120.0 mmol) in acetonitrile (200 mL) was stirred at room temperature for two hours. The resulting precipitate was collected by filtration to give the desired product, which was used without further purification.
