Prepared using General Procedure 2: To a stirring solution of N-(4-hydroxybenzyl)-4-nitrobenzamide INT-1 (647 mg, 2.38 mmol) in DCM (10 mL) at 0° C. was added TEA (1.03 mL, 7.13 mmol) followed by 4-(heptyloxy)benzoyl chloride (12.4 mL, 2.85 mmol). The suspension was sonicated until clear then diluted with DCM (50 mL) and washed with NaHCO3 (20 mL). The organic layer was concentrated and purified by chromatography (EA/hexanes) to provide 857 mg (73%) of 4-((4-nitrobenzamido)methyl)phenyl 4-(heptyloxy)benzoate INT-2. LCMS-ESI (m/z) calculated for C28H30N2O6: 490; found 491 [M+H]+, tR=3.41 min (Method 5).
