Versuchsvorschrift

Palladium acetate (12 mg), tris(4-methylphenyl)phosphine (24 mg), tri-n-butylamine (0.25 mL) were added to a DMF (1.2 ml) solution of (2S)-2-[(4-iodobenzoyl)(methyl)amino]-N,2-dimethyl-N′-(tetrahydro-2H-pyran-2-yloxy)propanediamide (Intermediate 15, 90 mg) and 4-ethenylbenzaldehyde (98 mg) obtained by the same method as the synthesis method described in the literature (Journal of Electroanalytical Chemistry, 2002, Vol. 529(1), pp. 43-50), and the mixture was stirred overnight at 80° C. The solvent was distilled off under reduced pressure, and the resulting residue was purified by OH type silica gel chromatography (gradient elution with chloroform/methanol=100/0→94/6) to obtain a crude product. Morpholine (30 μl) and acetic acid (20 μl) were added to a chloroform (1.0 ml) solution of the resulting crude product, and the mixture was stirred for 2.5 hours at room temperature. Further, sodium triacetoxyborohydride (62 mg) was added, and the mixture was stirred overnight at room temperature. A saturated aqueous solution of sodium hydrogen carbonate was added to the reaction mixture, the mixture was extracted with chloroform, and the organic layer was concentrated under reduced pressure. The resulting residue was purified by NH type silica gel chromatography (gradient elution with chloroform/methanol=100/0→94/6) to obtain (2S)-N,2-dimethyl-2-{methyl[(4-{(E)-2-[4-(morpholin-4-ylmethyl)phenyl]ethenyl}phenyl)carbonyl]amino}-N′-(tetrahydro-2H-pyran-2-yloxy)propanediamide (colorless oil) (32 mg, 31%).
