実験手順

A mixture of {5-[4-(4-methoxy-benzyl)-2,2-dimethyl-piperazin-1-ylmethyl]-pyridin-2-yl}-carbamic acid tert-butyl ester (Step 109.2) (1.88 g, 4.3 mmol), a 4 N solution of HCl in dioxane (25 mL) and MeOH (25 mL) was stirred for 22 h at rt. The reaction mixture was allowed to cool, quenched by addition of a saturated aqueous solution of NaHCO3 and extracted with DCM. The organic layer was washed with a saturated aqueous solution of NaHCO3, dried (Na2SO4), filtered and concentrated to provide 1.5 g of the title compound as a brown solid: ESI-MS: 341.3 [M+H]+;]+; tR=1.72 min (System 1).
