실험 절차
A stirred mixture of (2RS,5SR)-[5-(4-fluoro-phenyl)-1-(toluene-4-sulfonyl)-pyrrolidin-2-yl]-methanol (1.25 g, 3.58 mmol) and thionyl chloride (2 ml) was heated for 4 h at 80° C. aqueous work-up and crystallization from ethyl acetate/hexane yielded the title compound as an off-white solid (1.12 g, yield 85%), m.p. 130° C. and MS: m/e=367 (M+).
