Reaction Steps

The title compound of step 5 (260 mg, 1.93 mmol) was dissolved in DMF (5 mL) and cooled to 0° C. NaH (94 mg, 2.31 mmol) was added and the mixture was stirred for 30 min. Methyl iodide (146 μL, 2.31 mmol) was added and the mixture stirred at rt for 2 h. The volatile components were removed under vacuum and silica gel chromatography (PE/EtOAc=1:1) gave the title compound (192.6 mg, 67%) as a brown oil. 1H NMR (CD3Cl, 300 MHz): δ 7.13 (d, J=6.6 Hz, 1H), 6.13 (d, J=6.6 Hz, 1H), 3.53 (s, 3H), 2.79-2.85 (m, 4H), 2.01-2.11 (m, 2H).
