Reaction Steps

A mixture of the corresponding acrylic acid derivative of Example 5 (1.0 g.) and palladium-on-charcoal (0.25 g. of 10%) in ethanol (50 ml.) was shaken in an atmosphere of hydrogen until uptake of hydrogen had ceased. Removal of the catalyst by filtration, evaporation of the filtrate and recrystallisation of the residue gave 0.25 g. of the title compound.
