Procedure

A solution of 1.69 g (0.00768 mole) of 3-methoxy-2-naphthoic acid chloride in 15 ml of methylene chloride was added dropwise to a stirred solution of 0.97 g (0.00768 mole) of 3-aminoquinuclidine in 25 ml of methylene chloride in a closed system equipped with an oil bubbler. The reaction mixture was stirred overnight at ambient temperature, and then concentrated to give an off-white glassy solid. Two recrystallizations from methanol-isopropyl ether gave 1.95 g (73.4%) of the product as an off-white solid which was vacuum dried at ambient temperature, m.p. 248°-252° C.
