A solution of 1,5-bis-benzyloxy-2-isopropyl-4-azido-benzene (240 mg, 0.64 mmol) and t-butyl ethynyl(4-morpholinobenzyl)carbamate (185 mg, 0.58 mmol) in DMF (2.5 ml) was degassed at RT by means of three vacuum-nitrogen cycles before adding [Cp*RuCl]4 (32 mg, 0.029 mmol). The reaction mixture was stirred at RT until completion (i.e., monitored by TLC). AcOEt and H2O were then added. The organic phase was extracted four times with AcOEt, washed with water (three times) and brine (once) and dried over Na2SO4. The solvent was removed under reduced pressure and the reaction mixture was purified by column chromatography (PE/AcOEt:60/40). The title compound was obtained as an oil.
