    摘要: The present invention relates to a highly pure (2R,3S)-4-benzyl-3-(4-fluorophenyl)morpholin-2-yl 3,5-bis(trifluoromethyl)benzoate of Formula II, and a process for its preparation. The present invention further provides a process for preparation of Aprepitant of Formula I or pharmaceutically acceptable salt thereof, using the highly pure compound of Formula II. The present invention also provides a process for preparation of Aprepitant of Formula I or pharmaceutically acceptable salt thereof which comprises of cyclising the compound of Formula VII at elevated temperature, in the absence of solvent.
