The compound of Example 103 (250 mg, 0.57 mmol) in a solution of ethanol (10 ml) containing 6N aqueous NaOH (2.0 ml) was heated a reflux for 2 h. On cooling the ethanol was removed under reduced pressure and the basic solution brought to pH 5 with 2M hydrochloric acid. The resulting solution was concentrated under reduced pressure, and the residue taken up in hot ethanol (20 ml). This solution was filtered and the filtrate evaporated under reduced pressure to give a residue which was crystalised from ethanol to give the title compound (89 mg) as a white solid m.p. 144-150°. MS m/z 411 (M+H)+.
