Reaction Steps

tert-Butyl (3S,5R)-3-[{[1-(4-methoxybutyl)-1H-benzimidazol-2-yl]carbonyl}(propyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (2.19 g) was dissolved in 4M hydrogen chloride-ethyl acetate (20 ml), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was concentrated to give the object product (2.09 g).
