Reaction Steps

Under a static nitrogen atmosphere 2.40 g (4.7 mmol) of 5-[4′-[[3-butyl-5-(N-Boc-3-aminopropyl)-1H-1,2,4-triazol-1-yl]methyl][1,1′-biphenyl]-2-yl]-1H-tetrazole from Example 67 was dissolved in 30 mL of 4N HCl in dioxane at ambient temperature and allowed to stir overnight. The solvents were removed in vacuo; the residue was triturated with diethyl ether and filtered providing 2.08 g (98%) of 5-[4′-[[3-butyl-5-(3-aminopropyl)-1H-1,2,4-triazol-1-yl]methyl][1,1′-biphenyl]-2-yl]-1H-tetrazole as the hydrochloride salt: NMR (DMSO-d6) δ 0.88 (t, J=7 Hz, 3H), 1.25–1.39 (m, 2H), 1.57–1.69 (m, 2H), 1.92–2.40 (m, 2H), 2.62 (t, J=7 Hz, 2H), 2.89 (q, J=8 Hz, 2H), 2.98 (t, J=8 Hz, 2H), 5.38 (s, 2H), 7.10 (d, J=8 Hz, 2H), 7.19 (d, J=8 Hz, 2H), 7.54 (d, J=8 Hz, 1H), 7.59 (dd, J=8 and 2 Hz, 1H), 7.66 (s, 1H), 7.70 (dd, J=8 and 2 Hz, 1H), 8.10 (br s, 2H); MS (FAB) m/e (rel intensity) 417 (38), 389 (10), 357 (10), 207 (100), 166 (50), 139 (10) 115 (10); HRMS. Calc'd for M+H: 417.2515. Found: 417.2563.
