Procedure
80.2 g (0.24 mole) of 3-(4-aminobenzoyl)-7-benzyl-3,7-diazabicyclo[3.3.1]nonane (cf. European Pat. No. 62,199) were dissolved in 500 ml anhydrous tetrahydrofuran and cooled with ice. 23.5 g (0.3 mole) of acetyl chloride, dissolved in 50 ml of tetrahydrofuran, were added dropwise, followed by 48.6 g (0.48 mole) of triethylamine at room temperature. The entire mixture was stirred overnight and then evaporated down under reduced pressure. The residue was taken up in water and the solution was extracted 3 times with methylene chloride. The combined organic phases were washed with water, dried and evaporated down under reduced pressure. Yield: 78.1 g, mp.: 208° C.
