Procedure

A solution of 1-methylethyl((2S,4R)-1-acetyl-6-{1-[2-({[(1,1-dimethylethyl)oxy]carbonyl}amino)ethyl]-1H-imidazol-4-yl}-2-methyl-1,2,3,4-tetrahydro-4-quinolinyl)carbamate (for a preparation, see Intermediate 79) (47 mg, 0.094 mmol) in 1,4-dioxane (0.5 mL) was treated with HCl (4M in 1,4-dioxane, 2 mL, 8 mmol) and the resulting mixture was stirred at room temperature for 4 h. Et2O (10 mL) was added and the resulting mixture stirred for 15 min. The solid formed was filtered off, washed with Et2O and dried under house vacuum to give 1-methylethyl {(2S,4R)-1-acetyl-6-[1-(2-aminoethyl)-1H-imidazol-4-yl]-2-methyl-1,2,3,4-tetrahydro-4-quinolinyl}carbamate hydrochloride (25 mg, 0.057 mmol, 61%) as a brown solid.
