Reaktionsschritte
(R)-2-Methyl-propane-2-sulfinic acid [(S)-1-(6-isopropoxy-pyridin-3-yl)ethyl]-amide (2.90 g, 10.2 mmol) was dissolved in methanol (48 mL). A mixture of 12.0 M HCl in water (4.25 mL) and water (4.25 mL) was added drop wise over 3 minutes. The mixture was stirred at room temperature overnight. The mixture was evaporated to dryness. The oily residue was subjected to flash chromatography (silica, EtOAc/EtOH/triethylamine 90:5:5) on a short column to give (S)-1-(6-isopropoxy-pyridin-3-yl)-ethylamine IM24 (1.71 g, 93%) as a pale-yellow oil sufficiently pure for the next step. The overall yield from 1-(6-isopropoxy-pyridin-3-yl)-ethanone IM16 was 54%.
