Versuchsvorschrift

A solution of methyl 1-oxo-2-(2-oxoethyl)-1,2-dihydroisoquinoline-7-carboxylate (0.15 g, 0.61 mmol) and 3-(1H-pyrazol-1-yl)aniline (0.15 g, 0.92 mmol) in methanol (2 mL) was stirred at rt for 30 mins. Then acetic acid (3.5 μL, 0.06 mmol) and sodium cyanoborohydride (96 mg, 1.5 mmol) was added and the reaction mixture was stirred at rt overnight. The mixture was diluted with water and extracted with DCM (2×). The combined organic phases were then washed with water, and brine, dried over anhydrous Na2SO4, filtered and concentrated. The residue was purified by flash silica gel chromatography (20% to 70% EtOAc/hexanes) to afford methyl 1-oxo-2-(2-{[3-(1H-pyrazol-1-yl)phenyl]amino}ethyl)-1,2-dihydroisoquinoline-7-carboxylate (0.14 g, 59%). LC-MS: (FA) ES+ 389.
