Participants

Reaction Steps

A solution of 2-chloro-1-(2-isopropylpyrazolo[1,5-a]pyridin-3-yl)propan-1-one (0.9 g, 1 equivalent) and potassium thioacetate (0.61 g, 1.5 equivalents) in 4 mL of DMF was stirred at room temperature for 1 hour. The resulting solution was worked up with EtOAc and water. The crude product was purified by silica gel flash column chromatography to give S-1-(2-isopropylpyrazolo[1,5-a]pyridin-3-yl)-1-oxopropan-2-yl ethanethioate (0.58 g, 55% yield) as a yellow solid. Compound 1081.
