Procedure

4M aq. NaOH (10 mL, 40.2 mmol) was added to a RT solution of 3-methyl-2-(2H-1,2,3-triazol-2-yl)benzonitrile (1.48 g, 8.04 mmol) in MeOH (15 mL) and the resulting mixture was heated to 90° C. for 50 h. The reaction mixture was cooled to RT and diluted with water before the organic solvent was removed in vacuo. The remaining aqueous phase was acidified with 1M aq. HCl and extracted with EtOAc (3×). The combined organic phases were washed with brine, dried over Na2SO4, filtered and evaporated in vacuo to give the title compound that was used further without purification. LC-MS B: tR=0.50 min; [M+H]+=186.17.
