Reaction Steps

A mixture of benzenesulfonic acid lithium salt (32.8 g, 0.20 mmol) and 500 ml THF was stirred in an ice bath while 138 ml (0.22 mol) of n-butyllithium solution (1.6M in hexane) was added. After stirring at room temperature for 1 hour the mixture was recooled to 0° and cyclopentanone (16.8 g, 0.20 mmol) was added dropwise; the reaction mixture was allowed to warm to ambient temperature and stirred for 24 hours. The precipitated product was collected by filtration and dried in a vacuum oven to yield 39.8 g of 2-(1-hydroxycyclopent-1-yl)benzenesulfonic acid dilithium salt.
