Reaction Steps

4-Amino-N-[4-(2,4-di-t-pentylphenoxy)butyl]-1-hydroxy-2-naphthamide (11.7 g, 23.8 mmoles) was dissolved in methylene chloride (300 ml) under nitrogen and reacted with intermediate (B) (6.7 g, 25.2 mmoles) in the presence of pyridine (2.0 g). After 5 hours of stirring at room temperature, acetic acid (2 ml) was added and the mixture was evaporated to dryness. Trituration of the residue gave a solid which was collected by filtration and recrystallized from ethanol; yield, 8.0 g (46.8 percent).
