反応手順

To a solution of the compound of Example 12 (17.12 g, 0.11 mol) in ethanol (180 mL) in a Parr bottle, was added 4% Pd/C (3.43 g). The bottle was sealed, purged with nitrogen and was pressurized (5 psi) with hydrogen. After stirring at room temperature for 2 hr, the reaction vessel was vented, purged with nitrogen and filtered. The clear filtrate was concentrated to give the title compound (15.3 g, 90%). 1H NMR (CDCl3): 7.58 (dd, J=5, 2 Hz, 1H); 6.87 (dd, J=8, 2 Hz, 1H); 6.72 (dd, J=8, 5 Hz, 1H); 3.98 (s, 3H).
