Versuchsvorschrift

A mixture of 1,1-dimethylethyl{(1S)-2-{4-(bromoacetyl)phenyl]-1-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]ethyl}carbamate (1.90 g, 3.79 mmol), 1-(2-amino-3-pyridinyl)ethanol (0.523 g, 3.79 mmol), and solid sodium bicarbonate (0.398 g, 4.72 mmol) in isopropanol (24 mL) was refluxed for 3.0 h. The mixture was concentrated in vacuo and the residue dissolved in ethyl acetate, washed with water and saturated sodium chloride, dried (Na2SO4), and concentrated to give the title compound (1.79 g, 87%) as a light pink solid. MS (ES+) m/e 541 [M+H]+.
