To a pressure flask containing 5% Pd/C (91 mg, 0.085 mg) was added a solution of (S)-tert-butyl 7-nitro-3-(((R)-1,2,3,4-tetrahydronaphthalen-1-yl)carbamoyl)-3,4-dihydroisoquinoline-2(1H)-carboxylate (0.38 g, 0.85 mmol) in MeOH (8.5 mL). The resulting reaction mixture was stirred under 5 psi H2 for 1 h and then filtered through a pad of CELITE®, rinsing with EtOAc. The filtrate was concentrated in vacuo to give the title compound (301 mg, 84%) as a colorless oil. MS (ESI+) m/z 422.2 (M+H)+.
