Reaction Steps

5-(2,4-Bis-benzyloxy-5-isopropyl-phenyl)-4-(1′,3′-dihydro-spiro[[1,3]dioxolane-2,2′-inden]-5′-yl)-4H-[1,2,4]triazol-3-ol (550 mg, 0.93 mmol) was subsequently hydrodebensylated using Pd/C (10%, dry, 100 mg) and H2 in THF/MeOH (1/1, mL) at 1 atm at r.t. for 2 h. The reaction mixture was filtered through a pad of celite and the mother liquid was concentrated. It was again filtered through a pad of silica gel and the filtrate was concentrated to give the title compound as a white solid (370 mg, 97%).
