The compound obtained in Example 31 is dissolved in a methanol/dioxane mixture and then a catalytic amount of palladium-on-carbon is added. The reaction is stirred at ambient temperature under a hydrogen atmosphere for from 6 to 15 hours. The carbon is then filtered off and the solvents are removed by evaporation in vacuo. The resulting residue is recrystallised from methanol to yield the title product.
