実験手順

To 1-(5-bromo-3-(4-fluorophenoxy)pyridin-2-yl)thiourea (0.5 g, 1.5 mmol) in ethanol (50 mL) was added (S)-2-chloro-1-(2,2-dimethyl-1,3-dioxolane-4-yl)ethanone (0.34 g, 1.9 mmol) and the reaction stirred at 80° C. for 1 hr. The reaction was poured into water (250 mL) and then filtered. The solid was triturated with ethyl acetate and methanol. The solid was suspended in ethyl acetate (500 mL) and washed with 1 N NaOH (500 mL). The organics were concentrated and the crude material was purified by chromatography using 3 to 10% MeOH/CH2Cl2 as eluent to give (R)-1-(2-(5-bromo-3-(4-fluorophenoxy)pyridin-2-ylamino)thiazol-4-yl)ethane-1,2-diol (0.043 g, 0.10 mmol, 7%) (ABCI POS 426, 428 M+H).
