-78 °C

To a solution of 2-methyl-2-(4-pyridin-3-yl-imidazol-1-yl)-propionic acid ethyl ester (1 eq) in DCM at −78° C. was added diisobutylaluminum hydride (4 eq). After leaving the reaction mixture stir at −78° C. for 3 hours, methanol (4 eq) was added to the reaction mixture at −78° C. and the solution was warmed to room temperature over 60 minutes. Ethyl acetate was added to the solution and after 30 minutes the solution was filtered and concentrated to give 2-methyl-2-(4-pyridin-3-yl-imidazol-1-yl)-propionaldehyde (70%). MH++H2O (234)
