Procedure

A suspension of the product from step (c) (0.79 g) and 10% palladium on carbon (0.26 g) in a mixture of ethanol (15 ml), water (11 ml), ethyl acetate (2.0 ml) and aqu. 2N HCl (2.3 ml) was stirred under 1 atmos. pressure of hydrogen until uptake ceased. The mixture was filtered through Hyflo and the filtrate evaporated in vacuo to give the desired product as a pale yellow foam (0.79 g).

Workup

  1. filtrationThe mixture was filtered through Hyflo
  2. customthe filtrate evaporated in vacuo
