Versuchsvorschrift

A solution of the product of Example 1A (7.5 g, 32.61 mmol) in ethyl acetate (125 mL) was treated with 10% palladium on carbon (600 mg) and stirred at 25° C. under hydrogen gas for 18 hours. The solution was filtered through Celite® and the filtrate was concentrated in vacuo to give the title compound (7.63 g, 100%). 1H NMR (300 MHz, CDCl3): δ 7.27 (m, 5 H), 3.64 (m, 3 H), 1.96 (m, 4 H), 1.08 (m, 4 H), 0.89 (t, J=7.17 Hz, 6 H).
