실험 절차
A solution of Methyl 4-hydroxy benzoic acid (23-2) (Aldrich) (4.56 g, 30 mmol) in DMF (100 mL) was treated with Cs2CO3 (14.67 g, 45 mmol) at room temperature. After 0.5 hours, 3-bromo-1-chloropropane (5.94 mL, 60 mmol) was added and the solution was stirred for 4 hours. The reaction mixture was filtered and concentrated to give 27-1 as a white solid. Rf (10% EtOAc/hexanes) 0.36.
