実験手順
A solution of 94 mg (0.25 mmol) of trans-[4-(2-Chloro-ethylsulfanylmethyl)-cyclohexyl]-methyl-carbamic acid 4-chloro-phenyl ester in 1 ml DMA was treated with a catalytic amount of NaI and with 0.05 ml (0.5 mmol) of 2-ethylaminoethanol and stirred at RT for 16 h. The reaction mixture was stirred for 1 week, adding every day twice 0.05 ml (0.5 mmol) of 2-ethylaminoethanol. The solution was concentrated and the residual oil was extracted with aqueous sat. NaHCO3/Et2O (3×). The organic phases were washed with aqueous 10% NaCl solution and dried over Na2SO4 to yield after flash column chromatography on silica gel (CH2Cl2/MeOH 95:5) 40 mg (39%) of trans-(4-{2-[Ethyl-(2-hydroxy-ethyl)-amino]-ethylsulfanylmethyl}-cyclohexyl)-methyl-carbamic acid 4-chloro-phenyl ester, MS: 429 (MH+, 1Cl).
