Procedure

(2-Methyl-2-{4-[2-oxo-2-(4-oxo-1,4-dihydro-quinolin-3-yl)-ethyl]-phenyl}-propyl)-carbamic acid tert-butyl ester (88) (0.50 g, 1.15 mmol), TFA (5 mL) and CH2Cl2 (5 mL) were combined and stirred at room temperature overnight. The reaction mixture was then neutralized with 1N NaOH. The precipitate was collected via filtration to yield the product 3-(2-(4-(1-amino-2-methylpropan-2-yl)phenyl)acetyl)quinolin-4(1H)-one as a brown solid (651 mg, 91%). HPLC ret. time 2.26 min, 10-99% CH3CN, 5 min run; ESI-MS 336.5 m/z (MH+).
