実験手順
In analogy to the procedure described for example 1 a], 3-[2-methyl-5-(4-trifluoromethoxy-phenyl)-2H-pyrazol-3-yl]-propionic acid ethyl ester was reduced with lithium aluminium hydride in diethyl ether to give 3-[2-methyl-5-(4-trifluoromethoxy-phenyl)-2H-pyrazol-3-yl]-propan-1-ol as yellow oil.
