Reaction Steps

A mixture of 1.4 g of the compound obtained in step B of EXAMPLE 21 and 0.6 g of 4-benzylquinuclidine in 3 ml of DMF is heated at 80° C. for 2 hours. After cooling to RT, the reaction mixture is poured into water and extracted with AcOEt, the organic phase is washed with water, with 300 ml of 10% HCl solution and with 300 ml of saturated NaCl solution and dried over MgSO4 and the solvent is evaporated off under vacuum to give 1.35 g of the expected product after crystallization from AcOEt. M.p.=172°-175° C.
