Versuchsvorschrift

The product of step (b) (0.013 mole) was heated in NMP (25 ml) at reflux under nitrogen for 1 hour. After cooling to room temperature, the mixture was diluted with ethanol (25 ml), and hydrogenated over 5% Pd/C at 15-20 psi for 21/2 hours. After filtration, the mixture was poured into water, the grey solid isolated by filtration, and recrystallised from ethanol to give the title compound. Yield 63%, mp 114°-115° C.
