Procedure

To a solution of tert-butyl (2R,5R)-5-(aminomethyl)-2-[2-(2-{[N-(methoxycarbonyl)-β-phenyl-L-phenylalanyl]amino}phenyl)ethyl]morpholine-4-carboxylate (1 eq.) in DCM (0.1M) were added pyridine (3 eq) and benzene sulfonyl chloride (1.3 eq). The reaction mixture was stirred for 4 hrs at room temperature, diluted with CH2Cl2 and the organic layer was washed with aqueous saturated sodium bicarbonate. The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by automated silica gel flash chromatography system eluted with a gradient 10% to 100% of EtOAc/Hex to afford title compound.
