Procedure

A solution of the product of Preparation 3 (2.4 g) in glacial acetic acid (25 ml) was stirred with zinc (2.5 g) for 4 hours. The zinc was removed by filtration and washed with water (50 ml) and ether (50 ml). The filtrate and washings were brought to pH 10 with 0.88 NH3 solution and extracted with ether (×4). The extract was washed with water, dried and evaporated to leave a solid (1.65 g). A portion was crystallised from ether to give the title compound, m.p. 113°-116°, [α]D +38°
