Reaction Steps

To a suspension of 2.95 g (0.012 mol) of the product of Step A in 100 mL of water was added 15.1 g (0.0479 mol) of barium hydroxide octahydrate. The reaction was heated at reflux for 3 days. To the reaction mixture was carefully added 6.4 g (0.067 mol) of ammonium carbonate. Refluxing was continued for another 2 hours. The solid was filtered off while hot and the pH of the filtrate adjusted to 6. The filtrate was then concentrated to give 1.86 g of a tan solid: mp>250° C. 1H NMR (D2O) d 7.20 (d, 1H), 6.85 (d and s, 2H), 3.835 (s, 3H), 2.85 (t, 2H), 1.70-2.40 (m, 4H).
