A practical and scalable total synthesis of tachykinin NK3 receptor antagonist SR 142801, (R)-N-[1-[3-[1-benzoyl-3-(3,4-dichlorophenyl)-3-piperidinyl]propyl]-4-phenyl-4 -piperidinyl]-N-methyl acetamide 1 is described. The absolute configuration of the key intermediate 7 was determined by single crystal X-ray crystallography, on the basis of which, the absolute configuration of SR 142801 should be (R)-(+), instead of the recently reported (S)-(+).
