Participants

Reaction Steps

By essentially following the conditions described in Example 16, Part E, the free base of the title compound was prepared as a solid from 2-(4-aminophenyl)-3-[4-[2-(1-pyrrolidinyl)ethoxy]benzyl]benzo[b]thiophene (Example 16; Part D) and 3-pyrazole carboxylic acid in 48% yield following radial chromatography (SiO2; 1% then 3% then 5% MeOH in CHCl3 sat'd with NH4OH). The solid was taken up in 5 mL MeOH, and the solution was treated with 1 mL of 1 N HCl. The solution was concentrated to give the title compound.
