Aluminium lithium hydride → (R)-1-[(3S,4S)-1-Benzyl-3-(4-chloro-phenyl)-piperidin-4-yl]-ethanol

Participants

Reaction Steps

In analogy to the procedure described for the synthesis of (RS)-1-[(3SR,4SR)-1-Benzyl-3-(4-chloro-phenyl)-piperidin-4-yl]-ethanol (example 5 (d)) the title compounds were synthesized from 1-[(3S,4S)-1-Benzyl-3-(4-chloro-phenyl)-piperidin-4-yl]-ethanone through reduction with LiAlH4. (R)-1-[(3S,4S)-1-Benzyl-3-(4-chloro-phenyl)-piperidin-4-yl]-ethanol was obtained as light yellow viscous oil. MS (m/e): 330.1 [(M+H)+] and (S)-1-[(3S,4S)-1-Benzyl-3-(4-chloro-phenyl)-piperidin-4-yl]-ethanol was obtained as colorless foam. MS (m/e): 330.1 [(M+H)+]
