4-[(2R)-2-[(1S,3S,5S)-3,5-dimethyl-2-oxocyclohexyl]-2-hydroxyethyl]piperidine-2,6-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The same procedure as in (1) and (2) of Production Example 28 was repeated, except that the 6-benzyloxy-2-naphthaldehyde was replaced by 5-formyl-1-(tetrahydropyran-2-yloxy)indane, to obtain oily 2-[2-(N,N-dimethylamino)ethoxy]-1-[1-(tetrahydropyran-2-yloxy)indan-5-yl]ethanol (compound No. 294).
