Reaction Steps

30.8 g of (3-(4-methoxy-phenyl)-5-phenyl-(1,2,4)triazol-1-yl)-acetic acid methyl ester was dissolved in 140 mL dioxane and a solution of 0.8 g LiOH in 140 mL of water was added. The mixture was stirred for 4 h at RT. The mixture was acidified with HCl-solution and the precipitate was filtered to give 9.0 g of the desired product as mixture of isomers. These isomers were separated by HPLC chiral (method 1; solvent MeOH: DCM=1:1, concentration: 90 mg/mL). Rt: 1.26 min (method A) and 1.24 min., (M+H)+: 310
