Procedure

1,1-Dimethylethyl (2S)-4-[(4-{({6-[(4-fluorophenyl)oxy]-3-pyridinyl}carbonyl)[2-(methyloxy)ethyl]amino}phenyl)methyl]-2-methyl-1-piperazine carboxylate (D119) (0.077 g, 0.13 mmol) was dissolved in 4M HCl in dioxane (5 mL). A few drops of water were added and the reaction was stirred for 2 h. The solvent was removed in vacuo and the resulting yellow oil was dissolved in MeOH and loaded onto an SCX cartridge which was eluted with DCM, MeOH and 2M NH3 in MeOH. The ammoniacal fractions were combined and concentrated to give the title compound as a yellow oil (0.0667 g). MS (ES): MH+ 479.4.
