Participants

Reaction Steps

A solution of [2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-methanol (0.294 g, 0.91 mmol) and Dess-Martin periodinane (3.32 mL, 1.0 mmol, 3M solution in DCM) in DCM (15 mL) was stirred at RT for 1.5 h then washed with 1M sodium hydroxide. The aqueous phase was extracted with DCM and the combined organic extracts dried (Na2SO4) and concentrated in vacuo to give 2-(2-Isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene-8-carbaldehyde (0.35 g, quant.). LCMS: RT=3.07 min, [M+H]+=324.
