Reaction Steps

To a solution of 2-chloro-5-[2-chloroethoxy]-N-(tricyclo[3.3.1.13,7]dec-1-ylmethyl)-benzamide (Example 11a, 0.15 g) and N,N-diisopropylethylamine (0.50 ml) in 1-butanol (4 ml) was added sodium iodide (0.06 g) and 3-aminopropan-1-ol (0.09 ml). The reaction vessel was sealed and the mixture heated at 110° C. for 24 h. The reaction mixture was partitioned between ethyl acetate and sodium hydrogencarbonate solution, dried (MgSO4) and concentrated under reduced pressure. The residue was purified by RPHPLC (eluting with 25-95% MeCN/0.1% AcONH4 aqueous) to give 2-chloro-5-[2-[(3-hydroxypropyl)amino]ethoxy]-N-(tricyclo[3.3.1.13,7]dec-1-ylmethyl)-benzamide as the acetate salt. This was converted to the hydrochloride salt by stirring with 4M HCl in dioxane and concentration under reduced pressure. Recrystalisation from isohexane/isopropanol gave the title compound as a white solid (0.1 g).
