A mixture of tert-butyl 2-(trans-3-(benzyloxy)cyclobutyl)-1H-benzo[d]imidazole-1-carboxylate (0.47 g, 1.23 mmol), cyclohexene (0.080 g, 0.91 mmol), and 20 wt % Pd (dry basis) on carbon, Degussa type E101 NE/W (2.45 g) in ethanol (5 mL) under argon was heated to 65° C. for 6 h, cooled to RT, and filtered through Celite®. The filtrate was concentrated in vacuo and the resulting oil was purified by silica gel chromatography to give tert-butyl 2-(trans-3-hydroxycyclobutyl)-1H-benzo[d]imidazole-1-carboxylate (0.31 g, 1.09 mmol, 88% yield) as a white solid.
