Reaction Steps

Following a procedure analogous to that for the synthesis of Intermediate 223E, (E)-ethyl 2-(2-phenylhydrazono)acetate (133 mg, 0.690 mmol) and of (S)-tert-butyl 3-(3-((tert-butyldimethylsilyloxy)methyl)-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)-4-(2-nitrohex-1-enyl)benzoate (420 mg, 0.690 mmol) were converted to the title compound (335 mg, 65%). 1H NMR (CDCl3, 1:1 mixture of amide rotamers) δ 8.15-8.06 (m, 2H), 7.51-7.39 (m, 5H), 7.22-6.80 (m, 5H), 5.02-4.98 (m, 1H), 4.39-4.04 (m, 3H), 3.82-3.28 (m, 2H), 3.04-3.00 (m, 1H), 2.90-2.78 (m, 1H), 2.61-2.24 (m, 2H), 1.61 (s, 9H), 1.32-0.90 (m, 7H), 0.77 (s, 9H), 0.59 (t, J=8 Hz, 1.5H), 0.55 (t, J=8 Hz, 1.5H), 0.00 (s, 9H); MS(ESI+) m/z 752.4 (M+H)+.
