To a solution of 2-chloro-5-[3-chloropropoxy]-N-(tricyclo[3.3.1.13,7]dec-1-ylmethyl)-benzamide (0.25 g, Example 3a) and N,N-diisopropylethylamine (0.54 ml) in ethanol (5 ml) was added sodium iodide (0.08 g) and 1-propanolamine (0.24 ml). The reaction vessel was sealed and reaction mixture heated at 120° C. for 24 h. The reaction mixture was then concentrated under reduced pressure. The residue was partitioned between ethyl acetate and sodium hydrogencarbonate solution, and the aqueous phase extracted with additional ethyl acetate. The combined organic phases were dried (MgSO4) and concentrated under reduced pressure. The residue was purified by NPHPLC (eluting with 0-25% ethanol in dichloromethane) to give 2-chloro-5-[3-(3-hydroxy-propylamino)-propoxy]-N-(tricyclo[3.3.1.13,7]dec-1-ylmethyl)-benzamide as a semi-solid. This compound was converted to the hydrochloride salt by stirring with 4M HCl in dioxane and concentrated under reduced pressure to leave the title compound as a white solid (0.036 g).
