Reaktionsschritte
Following the procedure described for preparation of 29b. Starting from (S)-tert-butyl 1-oxo-1-(quinolin-3-yl)propan-2-ylcarbamate (42c, 1.6 g, 5.33 mmol), Aluminium isopropoxide (0.68 g, 3.33 mmol) and 2-propanol (4.5 mL, 59.16 mmol) in toluene (7 mL) stirred at +50° C. in sealed reaction tube flushed with argon for 16 hours. Work up and deprotection of the intermediate BOC-protected amine afforded the subtitle compound as a colourless solid. Yield 1.29 g (88%).
