Added 4M HCl/dioxane (5 ml) to solution of 5-Pyrimidin-2-yl-3′,6′-dihydro-2′H-[2,4′]bipyridinyl-1′-carboxylic acid tert-butyl ester (2Q) (110 mg, 0.325 mmol) in MeCl2 (5 ml) at room temperature, then stirred 4 hours. Evaporated solvent. Added MeCl2 (100 ml), H2O (50 ml) and 10% NaOH (3 ml). The organic layer was separated, dried over MgSO4, filtered and solvent evaporated yielding 3Q as a white solid (90 mg, 100%) ESMS (MH, 239) LCMS (MH, 239) Retention time=1.53 minutes.
