Procedure

To a solution of {2-[2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1,10b-diaza-benzo[e]azulen-9-yl}-methanol (370 mg, 1 mmol) in DCM (20 mL) was added Dess-Martin periodinane (467 mg, 1.1 mmol) and the reaction mixture stirred at RT for 30 minutes. The reaction mixture was diluted with DCM (20 mL) and the solution washed with sodium hydroxide solution (1 M, aqueous). The organic layer was separated, dried (MgSO4) and then concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 90% ethyl acetate in cyclohexane) to yield the title compound as a white solid (253 mg, 70%). LCMS: RT=4.10, M+H+=364
