Reaction Steps

Cyclopent-3-ene-1-ol (200 mg, 2.38 mmol) was dissolved in pyridine (2.5 ml) and p-toluenesulfonyl chloride (558 mg, 2.92 mmol) was added portionwise at 0° C. After the addition was completed the reaction mixture was stirred at 0° C. for 3 h and then kept in the fridge overnight. Then it was poured into to a mixture of ice and diluted HCl (pH ˜5). The solid was filtered off, washed with diluted HCl and dried to obtain the title compound as off-white solid (447 mg, 79%). MS (EI): 256.2 (M+NH4)+.
