Procedure

The compound obtained in (1) (1.75 g) was dissolved in methanol (30 mi). 10% Pd-C (0.30 g) was added and the mixture was stirred vigorously at room temperature under atmospheric pressure of hydrogen for 1.5 h. The catalyst was filtered off and the filtrate was concentrated to give the product (1.2 g) as a colorless foam.

Workup

  1. filtrationThe catalyst was filtered off
  2. concentrationthe filtrate was concentrated
