Reaction Steps

Following a procedure analogous to that for the synthesis of Intermediate 223E, (E)-ethyl 2-(2-(4-methoxyphenyl)hydrazono)acetate (24 mg, 0.108 mmol) and tert-butyl 4-(2-nitrohex-1-enyl)-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate (50 mg, 0.108 mmol) were converted to the title compound (31 mg, 45%) as a colorless oil. 1H NMR (CDCl3, 1:1 mixture of amide rotamers) δ 8.08 (dd, J=8, 2 Hz, 1H), 8.03-8.02 (m, 1H), 7.42-6.81 (m, 9H), 5.02-4.98 (m, 1H), 4.46-4.38 (m, 1H), 4.32-4.26 (m, 2H), 4.15-3.98 (m, 1H), 3.86 (s, 1.5H), 3.85 (s, 1.5H), 3.54-3.33 (m, 1H), 2.81-2.45 (m, 4H), 1.61 (s, 9H), 1.28 (t, J=8 Hz, 1.5H), 1.22 (t, J=8 Hz, 1.5H), 1.30-0.95 (m, 4H), 0.61-0.57 (m, 3H); MS(ESI+) m/z 638.3 (M+H)+.
