1-[6-(4-Fluoro-benzyl)-3,3-dimethyl-2,3-dihydro-pyrrolo[3,2-b]pyridin-1-yl]-2-[(2R,5R)-5-methyl-2-((R)-3-methyl-morpholin-4-ylmethyl)-piperazin-1-yl]-ethanone (1.72 g) was dissolved in EtOAc (40 mL) then treated dropwise with a mixture of 4 M HCl in dioxane and EtOAc (40 mL) while stirring at ambient temperature. The resulting clear solution was allowed to stand for 64 h then was evaporated in vacuo to give a foam which was dissolved in isopropanol then re-evaporated. The resulting residue was triturated with ether to afford the title compound (1.43 g) as a white powder. 1H NMR (Me-d3-OD): 8.19 (1H, s), 8.13 (1H, s), 7.31-7.19 (2H, m), 7.04 (2H, t), 4.16-3.79 (7H, m), 3.79-3.42 (4H, m), 3.02 (5H, m), 2.61-1.92 (2H, m), 1.42 (6H, d), 1.32 (3H, s), 1.17 (3H, d), 1.16-0.77 (3H, m).
