Versuchsvorschrift

Prepared using General Procedure 7. Into a stirring solution of (S)-2-(4-(3-(tert-butoxy)-2-(4-(tert-butyl)benzamido)-3-oxopropyl)phenyl)pyrimidine-5-carboxylic acid (50 mg, 0.10 mmol) in DCM (2 mL) were added EDC (34 mg, 0.20 mmol), DMAP (3 mg, 0.02 mmol) and heptanehydrazide (16 mg, 0.11 mmol). After 18 h, the reaction mixture was diluted with NaHCO3 and extracted with DCM (2×). The organic layers were combined, dried (Na2SO4), concentrated and purified by chromatography (EA/Hexane) to provide 38 mg (61%) of tert-butyl (S)-2-(4-(tert-butyl)benzamido)-3-(4-(5-(2-heptanoylhydrazine-1-carbonyl)pyrimidin-2-yl)phenyl)propanoate. LCMS-ESI (m/z) calculated for C36H47BN5O5: 629.8; no m/z observed, tR=3.84 min (Method 1). 1H NMR (400 MHz, CDCl3) δ 9.17 (s, 2H), 8.42 (d, J=8.2 Hz, 2H), 7.69 (d, J=8.4 Hz, 2H), 7.43 (d, J=8.4 Hz, 2H), 7.34 (d, J=8.2 Hz, 2H), 6.70 (d, J=7.3 Hz, 1H), 5.01 (dd, J=12.6, 5.8 Hz, 1H), 3.41-3.20 (m, 2H), 2.35 (t, J=7.5 Hz, 2H), 1.81-1.61 (m, 2H), 1.59 (d, J=14.0 Hz, 2H), 1.45 (s, 4H), 1.42-1.22 (m, 18H), 0.88 (t, J=6.8 Hz, 3H).
