Reaction Steps

Phenol from step 3 (500 mg, 2.3 mmol), 3-bromo-1-chloropropane (720 mg, 4.6 mmol) and K2CO3 (950 mg) in CH3CN (25 mL) was stirred at reflux 20 h. The reaction was filtered and concentrated. The resulting oil was dissolved in Et2O, and washed with water, NaCl solution, dried (MgSO4) and concentrated. The product was triturated with Et2O-hexanes to yield 580 mg (91%) mp 186-187° C. 1H NMR (DMSO-d6) δ 2.2 (t, 2H), 3.7 (s, 3H), 3.8 (t, 2H), 4.15 (t, 2H), 7.0-7.1 (m, 3H), 7.8 (d, 2H), 8.0 (d, 1H). MS m/z=279 (M+H).
