Reaction Steps

According to the procedure described in Example 6A Step 1, a mixture of ethyl 3,4-dihydroxybenzoate (5.465 g, 30 mmol), bromoethane (7.192 g, 66 mmol), and K2CO3 (9.122 g, 66 mmol) in DMF (50 mL) was heated at 50° C. for 5 hours, to afford ethyl 3,4-diethoxybenzoate as solid (6.439 g, 90%). 1H NMR (300 MHz, CDCl3) δ 7.65 (dd, 1H), 7.55 (d, 1H), 6.87 (d, 1H), 4.35 (q, 2H), 4.15 (q, 4H), 1.48 (m, 6H), 1.38 (t, 3H); LC-MS (ESI) m/z 239 (M+H)+.
