Reaction Steps

The acid prepared in Example 5 (0.5 g, 1.1 mmol) was dissolved in methanol (15 ml) and stirred under an atmosphere of hydrogen for 8 h at room temperature in the presence of 10% palladium on carbon catalyst (50% aqueous paste). The mixture was filtered and the solvent was evaporated in vacuo to give an oily residue which was re-evaporated from acetone and then crystallised from a mixture of acetone and ethyl acetate. This afforded 0.3 g (60%) of the title compound as an amorphous solid.
