Reaktionsschritte

To a solution of compound 37 (425 mg, 1.43 mmol) dissolved in 20 mL of anhydrous THF in a Parr apparatus for hydrogenation, was added 160 mg of 10% Pd/C, the system was charged with 60 psi of H2, and the bottle was shaken for 2 h. The catalyst was filtered over Celite, washed with 20 mL of ethyl acetate and the combined filtrate was concentrated in vacuo to give 38 (180 mg, 77%). 1H NMR (400 MHz, CDCl3) δ 3.36 (s, 6H), 3.42 (s, 2H), 4.08 (d, J=5.3 Hz, 2H), 4.54 (t, J=5.3 Hz, 1H).
