Reaction Steps
A mixture of 1-ethyl-5-(pyrrolidin-1-yl)-3-((trimethylsilyl)ethynyl)-1H-1,2,4-triazole (122 mg, 465 μmol, Eq: 1.00) in methanol (3 ml) and 1N NaOH aq. (0.1 ml) was stirred for 18 hours at 25° C. under argon atmosphere. The mixture was diluted with ethyl acetate and washed with water. The organic layer was separated, dried over magnesium sulfate, filtered and concentrated affording 1-ethyl-3-ethynyl-5-pyrrolidin-1-yl-1H-[1,2,4]triazole (79 mg, 89.3%) as an orange oil. MS: m/z=191.2 (M+H+)
