Procedure

To a nitrogen flushed solution of the title compound from Step A (1 g, 8.39 mmol) in methanol (40 ml) was added 10% palladium on carbon (100 mg) and the resulting mixture stirred under a balloon of hydrogen for 3 h. The mixture was filtered through celite and evaporated to give 950 mg (91%) of the title compound (i-6) as an orange oil. 1H NMR (CDCl3): 2.54 (s, 3H), 4.16 (s, 2H), 7.03 (d, J 5.0 Hz, 1H), 8.56 (d, J 5.0 Hz, 1H).
