実験手順

A mixture of 2-amino-5-chlorothiazole (2.00 g, 14.9 mmol), 1-adamantanecarbonyl chloride (3.54 g, 17.8 mmol), 4-dimethylaminopyridine (1.10 g, 0.90 mmol) and triethylamine (4.15 mL, 23.0 mmol) in 80 mL of THF was stirred at 80° C. for 48 hours The mixture was cooled to ambient temperature, diluted with 100 mL of ethyl acetate and washed with brine. The layers were separated and the aqueous phase was extracted twice with 50 mL of ethyl acetate. The combined organic extracts were dried over anhydrous Na2SO4, filtered, and concentrated. Purification by column chromatography (SiO2, dichloromethane) afforded 2.27 g of the title compound: MS (DCI/NH3) m/z 297 (M+H)+.
