Reaction Steps

6-Nitro-2-isopropyl-3-[(2'-(N-triphenylmethyl-tetrazol-5-yl)-biphen-4-yl)-methyl]-quinazolin-4-(3H)-one was hydrogenated overnight at 1 atm H2 in dioxane solution in presence of Raney nickel catalyst as described above. The product was purified by flash chromatography over silica gel eluting with CH2Cl2 /MeOH-20/1 to give a pale yellow solid. 1H-NMR (CDCl3): 1.20, (d, 6H, J=6.4 Hz), 2.89-3.06, (m, 1H), 5.34, (br.s, 2H), 6.85-7.68, (m, 24H), 7.84-7.92, (m, 1H).
