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]azulene-9-carboxylic acid methyl ester (393 mg, 1 mmol) in THF (10 mL) at −70° C. was added DIBAL (3 mL, 1 M solution in toluene, 3 mmol) and the reaction mixture stirred at 0° C. for 1 h. The reaction mixture was diluted with methanol (5 mL), then with saturated aqueous sodium potassium tartrate solution. The resultant mixture was extracted with ethyl acetate (3×20 mL), then the combined organic fractions dried (MgSO4) and concentrated in vacuo to give the title compound (370 mg, 100%).
