Reaction Steps

To a solution of 68 (5.8 g, 34.9 mmol) in CH3CN (150 ml) was added K2CO3 (10.6 g, 76.8 mmol). The mixture was added benzyl bromide (6.57 g, 38.39 mmol) and refluxed for 8 h under N2 atmosphere. The reaction mixture was cooled to 25° and poured into H2O (500 ml), and then extracted with CH2Cl2. The organic layer was washed with H2O, dried over MgSO4 and evaporated. The crude products were purified by distillation to give 73 as colorless liquid. (8.5 g, 33.2 mmol).
