実験手順

DIPEA (7.5 mL) was added to a suspension of 3-{(phenylmethyl)oxy}-5-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethoxy)benzoic acid (4.5 g, 0.011 mol), HATU (8.6 g, 0.023 mol) and 2-amino-5-methylthiazole (2.46 g, 0.022 mol) in DMF (70 mL). The resulting mixture was stirred at ambient temperature for 72 hours. The DMF was removed in vacuo. Water (100 mL) was added and the mixture extracted with ethyl acetate (3×50 mL). The extracts were combined and washed with brine (100 mL). The solution was dried (MgSO4), filtered, and evaporated in vacuo to give the crude product which was chromatographed on silica, eluting with a gradient of 50-100% ethyl acetate in isohexane, to give the desired compound. (1.7 g).
