Procedure
4-Amino-1-butanol (0.11 ml) was added to a solution of 2-chloro-5-[3-[(methylsulfonyl)oxy]propyl]-N-(tricyclo[3.3.1.13,7]dec-1-ylmethyl)-benzamide (0.25 g, Example 6e) in tetrahydrofuran (4 ml) and heated at 60° C. in a sealed tube for 12 h. On cooling to ambient temperature, the mixture was diluted with ethyl acetate and extracted twice with saturated aqueous sodium hydrogencarbonate solution and once with brine, dried over magnesian sulfate and concentrated under reduced pressure. Purification by preparative reverse phase HPLC (eluting with a gradient of acetonitrile in 0.1% aqueous ammonium acetate/25–95%) gave the title compound as the acetate salt. Treatment with aqueous 2M sodium hydroxide and extraction into ethyl acetate gave the title compound (0.065 g).
