Reaction Steps

A suspension of ethyl 2-bromothiazole-5-carboxylate (0.125 mL, 0.834 mmol), title compound 216 (425 mg, 1.525 mmol), and triethylamine (0.465 mL, 3.34 mmol) in dioxane (1.525 mL) was sonicated for 1 h. More THF (2 mL) was added and the mixture was sonicated for another 2 h. The mixture was partitioned between water and ethyl acetate and the organic layer was washed with water (×2) then with brine. The organic extract was dried (magnesium sulfate) and solvent evaporated. The residue was purified via ISCO (0-50% Hex/EtOAc; 40 g silica gel column) to obtain title compound 217 (316 mg, 95%) as a white foam. LRMS: (calc) 397.11. (found) 398.1 (MH)+.
