Reaction Steps

To a solution of 1-methyl-4-phenyl-1H-[1,2,3]triazole (165 mg, 1.04 mmol) in THF (5.2 mL) was added n-BuLi (1.6 M in hexane, 777 μL, 1.24 mmol) dropwise at −75° C. under Argon. The resulted orange solution was stirred at −75° C. for 40 min, then DMF (104 μL, 1.35 mmol) was added dropwise at −75° C. and the reaction mixture was allowed to warm up to room temperature over 1 h. The mixture was then poured into saturated ammonium chloride solution and extracted with ethyl acetate and the combined organic extracts washed with brine, dried over sodium sulphate, filtered and evaporated. Purification by chromatography (silica, 0 to 50% ethyl acetate in heptane) afforded the title compound (131 mg, 68%) as a white solid. MS: m/e=187.0 [M]+.
