Reaction Steps

To a solution of 2-(((1H-imidazol-4-yl)methyl)(4-methoxybenzyl)amino)ethanol (Step B, 14.5 g, 55.55 mmol) in anhydrous dioxane (100 mL) was added thionyl chloride (16.5 mL, 222.2 mmol) over a 10 minute period. The reaction mixture was heated at 60° C. for 3 hours, cooled to room temperature and partitioned under reduced pressure. The contents of the flask were azeotroped with dioxane (2×100 mL) and toluene (2×100 mL). The white solid c that separates out is filtered and used as such for the subsequent step without further purification (19.0 g).
