To a solution of 5-(benzyloxy)-1H-indazole (1 g, 4.5 mmol) in DMF (16 ml) at0 C was added NaH (60%, 0.27 g, 6.7 mmol). The resulting solution was stirred at 0 C for30 minutes before addition of <strong>[253176-94-2]tert-butyl 3-(iodomethyl)azetidine-1-carboxylate</strong> (1.3 g, 4.5mmol). The resulting solution was stirred at room temperature for 5 hours. After quenchingby addition of water, the mixture was partitioned between EtOAc (200 mL) and water (100mL), and the organic phasse was washed with saturated NaHCO3 (3xlOOmL), dried over Na2504, concentrated and the residue was purified on silica gel column using EtOAc/hexane as eluting solvents to give tert-butyl 3-((5-(benzyloxy)-2H-indazol-2-yl)methyl)-azetidine- 1- carboxylate.
