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 dihydrochloride (1.8 g) was dissolved in water (50 mL) and the resulting solution extracted with ethyl acetate (50 mL). The aqueous phase was basified (pH 8) with saturated aqueous NaHCO3 then was extracted with DCM (5×50 mL). The combined DCM extracts were dried (Na2SO4) and evaporated in vacuo to give the title compound (1.72 g) as a foam. 1H NMR (Me-d3-OD): 8.24 (1H, s), 8.07 (1H, d), 7.24 (2H, dd), 7.03 (2H, t), 4.19-4.06 (1H, m), 3.99 (3H, d), 3.90 (1H, d), 3.71 (1H, d), 3.65-3.48 (2H, m), 3.19-2.70 (8H, m), 2.60-2.40 (2H, m), 2.26 (1H, s), 2.09-1.93 (1H, m), 1.87 (1H, d), 1.41 (6H, d), 1.04 (3H, d), 0.97 (3H, d).
