Reaction Steps

Piperidine in methanol (20%; 2 mL) was added to {1-(4-tert-butoxy-benzyl)-2-oxo-2-[3-(4-phenyl-1H-imidazol-2-yl)-3,4-dihydro-1H-isoquinolin-2-yl]-ethyl}-carbamic acid 9H-fluoren-9-ylmethyl ester (0.20 g, 0.28 mmol) at room temperature. After 30 minutes the reaction was concentrated under reduced pressure, and the residual 200 mg of desired product 2-amino-3-(4-tert-butoxy-phenyl)-1-[3-(4-phenyl-1H-imidazol-2-yl)-3,4-dihydro-1H-isoquinolin-2-yl]-propan-1-one was used as is without further purification (LC/MS; Measured, MW (MH+):495).
