Reaction Steps

A mixture of 1.44 g of 8-(p-chlorophenylsulfonamido)-4-[3-(3-pyridyl)propyl]-octanamide (example 24) and 0.52 ml pyridine in 5.8 ml dioxane is cooled to 0° and 0.51 ml trifluoroacetic anhydride is added over a period of 1 h. The mixture is then stirred at room temperature for 3 h. The reaction is quenched by the addition of saturated aqueous sodium bicarbonate solution and extracted with methylene chloride (2×20 ml). The combined organic extracts are dried, filtered and evaporated to give 8-(p-chlorophenylsulfonamido)-4-[3-(3-pyridyl)propyl]-octanenitrile.
