Procedure

32.0 g (0.145 mol) of ethyl 6-methoxy-indan-1-one-2-carboxylate [cf. H. O. House, C. B. Hudson, J. Org. Chem. 35 (1970) 3, 647-651] are hydrogenated with 20 bar of H2 at 50° C. for 5 h in 180 ml of MeOH in the presence of 5 g of palladium/carbon (5% strength) as a catalyst. The catalyst is filtered off, the methanol is stripped off in vacuo and the residue is distilled in a bulb tube furnace.

Workup

  1. filtrationThe catalyst is filtered off
  2. distillationthe residue is distilled in a bulb tube furnace
