Procedure
The compound, 3-benzyl-3-azabicyclo[3.1.0]hex-6-yl-(4-bromobutyl)-carbamic acid t-butyl ester, 211.5 mg, 0.5 mmole, 1 eq (prepared by reacting boc-protected 3-benzyl-3-azabicylo[3.1.0]hex-6-yl amine, which in turn, was prepared following the procedure of T. F. Braish et al., Synlett, 1996, 1100, with 1-bromo-3-chloropropane) was dissolved in xylene (15 ml). To the reaction mixture, 3-(2-methoxy-5-methylphenyl)-3-phenyl propionic acid (203 mg, 0.75 mmole, 1.5 eq) and 1,8-diazabicyclo[5.4.0]undec-7-ene (0.75 mmole, 1.5 eq) were added. The resulting reaction mixture was refluxed for 2 hrs. Xylene was removed under reduced pressure and the residue was purified by column chromatography by using ethyl acetate in hexane solvent system to yield the compound, 3-(2-methoxy-5-methylphenyl)-3-phenyl propionic acid 4-[(3-benzyl-3-azabicyclo[3.1.0]hex-6-yl)-ethoxy carbonylamino]butyl ester.
