2-[3,5-bis(trifluoromethyl)phenyl]-N-{6-[(7S,9aS)-7-({[(1,1-dimethylethyl)(dimethyl)silyl]oxy}methyl)hexahydropyrazino[2,1-c][1,4]oxazin-8(1H)-yl]-4-[2-(hydroxymethyl)phenyl]-3-pyridinyl}-N,2-dimethylpropanamide (D61, 24.6 mg, 0.0315 mmol) was suspended in dry MeOH (1 mL) before adding c.HCl solution (5 drops). The reaction mixture was then stirred at R.T. for 3 hours. Poured directly onto a 5 g SCX column, washing with MeOH (2×10 mL) before eluting the compound off with NH3 in MeOH (4×10 mL). Solvent evaporated. Residue purified on a 5 g sek pak column eluting with 0-100% EtOAc/Pent followed by 0-10% MeOH/EtOAc. Solvent evaporated to afford the title compound as a colourless gum.
