実験手順: A solution of 1.02 g (3.00 mmol) of trans-4-{2-[(4-chloro-phenoxycarbonyl)-methyl-amino]-ethyl}-cyclohexanecarboxylic acid in 30 mL of CH42Cl2 was treated at RT with 2 drops of DMF, followed by 0.28 mL (3.30 mmol, 1.1 eq) of oxalyl chloride within 5 min, and stirring was continued for 90 min. The solution was evaporated, redissolved in 15 mL of CH2Cl2 and added to a solution of 0.80 g (9.00 mmol, 3 eq) of 3-(methylamino)-1-propanol [Powell et al., Synthesis (4) 338-340 (1986)]and 2.09 mL (15.00 mmol, 5 eq) of Et3N in 12 mL of CH2Cl2 at 0° C. The reaction was kept at RT for 1 h then partitioned between Et2O (×3)/ aqueous saturated NaHCO3. The organic phases were washed once with aqueous 10% NaCl, dried over Na2SO4 and evaporated. Purification by flash-chromatography on 90 g silica gel (EtOAc:CH2Cl2 1:1 to 4:1) gave 0.95 g (77%) of pure trans-(2-{4-[(3-hydroxy-propyl)-methyl-carbamoyl]-cyclohexyl}-ethyl)-methyl-carbamic acid 4-chloro-phenyl ester, MS: 411 (MH+, 1Cl).
