Reaction Steps

A solution of 1-benzyl-5-hydroxy-1-azoniabicyclo[3.2.1]octane chloride (D7a, 3.05 g, 0.012 mole) in dry DMF (100 ml) under nitrogen was treated with sodium hydride (600mg of 80% oil dispersion, 0.020 mole) and stirred at room temperature for 40 min. The mixture was then treated with bromoethane (4.7 ml, 0.063 mole) and stirred at room temperature for 16h. The excess sodium hydride was destroyed by addition of ethanol (5 ml) and the mixture acidified with glacial acetic acid (5 ml) and then concentrated in vacuo to give an orange semi-solid containing the title compound (D8). This was used in the next step without any purification.
