Reaction Steps
The product from Step 1 above (0.55 g, 2.0 mmol) was added to a stirred solution of NaO-t-Bu (0.55 g, 2.0 mmol) in DME (5 mL). After 5 min, β-bromophenetole (0.56 g, 2.8 mmol) was added, and the reaction was stirred at 55° C. for 15 h. 2 M HCl was added, and the reaction mixture was stirred for another 3 h. The reaction mixture was concentrated in vacuo and the residue was partitioned between 2 M NaOH/CHCl3. The aqueous phase as extracted with CHCl3 (×3). The combined organic lasers were dried (MgSO4), concentrated, and the residue was purified by chromatography on silica gel using CHCl3/MeOH/NH4OH (90:10:0.4) as eluent to give the free base of the title compound. The free base was treated with HCl/ether, and the resulting hydrochloride salt was dried (80° C., 1 mmHg) to afford 0.254 g (35%) of the title compound as a light brown semi-solid material that solidified upon standing. Anal. (C18H22N2O2.HCl.H2O) H, N; C. calc, 61.27; found, 61.9.
