Reaction Steps

195 mg of N-[(1S,2R)-1-benzyl-2-hydroxy-3-{[3-(trifluoromethyl)benzyl]-amino}propyl]-6-chloro-4-oxo-3-(1-propylbutyl)-3,4-dihydroquinazoline-8-carboxamide, 5 cm3 of dioxane and 30 mg of 10% (50% wet with water) palladium on carbon are stirred under 10 bar of hydrogen in an autoclave. Since the reaction does not develop, 30 mg of 10% dry palladium on carbon are added and the reaction mixture is stirred under 15 bar of hydrogen in an autoclave. The catalyst is filtered and the filtrate is concentrated under reduced pressure (5 kPa). 185 mg of N-[(1S,2R)-1-benzyl-2-hydroxy-3-{[3-(trifluoromethyl)benzyl]amino}propyl]-4-oxo-3-(1-propylbutyl)-3,4-dihydroquinazoline-8-carboxamide are obtained.
