(4-Hydroxymethyl-benzyl)-carbamic acid tert-butyl ester (480 mg, 0.71 mmol) was dissolved in DCM (3 mL) and cooled to −78° C. (dry ice/acetone). Dess-Martin periodinane (331 mg, 0.78 mmol) was added to the reaction which was allowed to warm to r.t and stir for 3 h. A 1:1 solution of saturated sodium bicarbonate and sodium sulfite (20 mL) was added and the reaction mixture stirred vigorously for 15 min. The organic layer was isolated, washed with saturated sodium bicarbonate (10 mL), dried (Na2SO4) and evaporated to dryness to afford the desired compound (480 mg, 100%). m/z 258 [M++Na]+
