Reaction Steps

1,3-Diethyl-5-(1-oxiranylmethyl-3-m-tolyl-1H-pyrazol-4-yl)-1,3-dihydro-benzoimidazol-2-one (obtained using a method similar to that for [4-(1,3-Diethyl-2-oxo-2,3-dihydro-1H-benzoimidazol-5-yl)-3-m-tolyl-pyrazol-1-yl]-acetaldehyde, substituting epibromohydrin for allyl iodide) (0.016 g) was diluted with diethylamine (0.3 mL, as a 70% solution in water) and stirred at 23° C. for 0.5 hours. Azeotropic removal of the water with toluene gave 1,3-Diethyl-5-[1-(3-ethylamino-2-hydroxy-propyl)-3-m-tolyl-1H-pyrazol-4-yl]-1,3-dihydro-benzoimidazol-2-one.
