Reaction Steps

The reaction mixture compound 12.2 (2.80 g, 9.45 mmol) and Pd/C (0.40 g, wt 10% on activated carbon) in EtOH (35 mL) was purged with hydrogen three times and stirred under hydrogen at ambient temperature overnight. The catalyst was removed by filtration. The filtrate was evaporated to give the crude compound 12.3 which was used in the next step without further purification. MS ESI (pos.) m/e: 209 (M+H). 1H NMR (CDCl3) δ 7.02(d, 2H), 6.75(d, 2H), 4.11(q, 2H), 2.93(dd, 1H), 2.68(m, 2H), 1.21(t, 3H), 1.16(d, 3H).
