실험 절차

The product from Example 70E (87 mg, 0.17 mmol) in dichloromethane (1.8 mL) was treated with trifluoroacetic acid (1.0 mL) at ambient temperature. After stirring for 2 hours, the mixture was concentrated and treated with aqueous 10% K2CO3 (2.4 mL). The aqueous solution was extracted with ethyl acetate (3×3 mL). The ethyl acetate extracts were combined and treated with 4-nitrophenyl 1,3-thiazol-5-ylmethyl carbonate [prepared from 4-nitrophenyl 1,3-thiazol-5-ylmethyl carbonate hydrochloride salt (100 mg, 0.36 mmol) by extraction with aqueous NaHCO3] in ethyl acetate (6 mL). After heating at 60° C. for 18 hours, the mixture was allowed to cool to ambient temperature and concentrated. The residue was purified by flash column chromatography on silica gel eluting with (chloroform:methanol, 98:2) to provide the title compound (33.5 mg, 31%). 1H NMR (CDCl3) δ 8.76 (s, 2H), 7.85 (s, 2H), 7.32-7.09 (m, 10H), 5.37-5.17 (m, 6H), 4.15 (br s, 2H), 3.61-2.65 (m, 10H), 1.24 (t, 3H); MS (ESI+) m/z 594 (M+H)+.
