Reaction Steps
A 0.75 g of 2-(1,4-dihydrothieno[2′,3′:4,5]cyclopenta[1,2-c]pyrazol-1-yl)ethyl methanesulfonate was dissolved in 10 ml of dimethylformamide, 0.47 g of sodium azide was added, and the mixture was stirred at 70° C. for 17 hours. After cooling, the reaction solution was poured into ice water and extracted with ether. The organic layers were combined, washed with brine and then dried with anhydrous magnesium sulfate. After removal of the drying agent, the solvent was concentrated under a reduced pressure to give 0.56 g of 1-(2-azidoethyl)-1,4-dihydrothieno[2′,3′:4,5]cyclopenta[1,2-c]pyrazole.
