Reaction Steps

Dissolve [1-(3,5-bis-trifluoromethyl-benzyl)-5-morpholin-4-yl-1H-[1,2,3]triazol-4-yl]-morpholin-4-yl-methanone in THF. Cool to −78° C., slowly add 28.3 ml (4 eq) of 1M diisobutyl aluminum hydride in toluene, and stir 2.5 hours. Move to 0° C. ice bath and allow reaction to slowly warm while stirring overnight. Slowly quench by adding ˜5 ml 1N HCl while still at 0° C. then warming to RT. Pour into 50 ml 1N NaOH. Extract with EtOAc, then wash organic layer with 1N HCl. Concentrate organic layer to give the desired aldehyde, which can be used without further purification. MS (IS) 409.2 (M+1). Rf=0.61 (1:1 Hexanes:EtOAc)
