Procedure
The product (6.4 g, 0.02 mol) of Stage 2 was dissolved in methanol(100 ml) and to this solution was added sodium borohydride (0.2 g, 0.005 mol) at 0°. After stirring at room temperature for 15 hours the methanol was removed in vacuo. The residue was washed with water and neutralised with dilute hydrochloric acid. Recrystallisation of the solid from petroleum ether/ethanol gave the title compound as white needles, m.p. 156°-160°.
