Reaction Steps
2-Furancarboxylic acid (12.6 mg, 0.11 mmol) was activated overnight at about 22° C. with carbonyldiimidazole (0.11 mmol, 0.2M in chloroform). 2-{(1S)-1-Amino-2-[indol-3-yl]ethyl}-4-phenyl-1H-imidazole (0.1 mmol, 0.5M in chloroform) was added to the media and the mixture was stirred for about 12 hours at about 22° C. Aminomethylated resin was then added (50-60 mg, 1.2 mmol/g, Novabiochem) in order to quench the excess of acylating agent for about 12 hours. Purification on silica gel pad (200 mg, Alltech) with ethyl acetate as eluent gave the expected product (37.2 mg, 94%). 1H-NMR (CDCl3, 100 MHz) δ: 8.36 (br s, 1H); 7.67-6.4 (m, 16H); 5.48 (qd, J=7.1 Hz, 1H); 3.6 (ABX system, 2H). LC/MS: m/z=397 (M+H).
