Participants

Reaction Steps

To a stirring solution of {(2S)-1-[cis-4-(4-fluorobenzyl)cyclohexyl]pyrrolidinyl}methanol and {(2S)-1-[trans-4-(4-fluorobenzyl)cyclohexyl]pyrrolidinyl}methanol (390 mg, 1.34 mmol) in 5 ml of methylene chloride at 25° C. under N2 was added pyridine (0.22 ml, 2.75 mmol, EM Science) followed by p-toluenesulfonyl chloride (288 mg, 1.51 mmol, Aldrich). Worked up after 16 hours by adding ethyl acetate then rinsing 3 times with sat'd sodium bicarbonate followed by 1 time time with brine. The organic was dried over magnesium sulfate, and concentrated in vacuo to obtain an oil which was purified over silica gel in 100% ethyl acetate to yield 87 mg of product. MS (ESI) detects 310 (M+H). The other isomer was isolated and used for example 16.
