実験手順
A catalytic amount of molecular sieves powder (4A) was added to the mixture of 2-butylaminothiazole (1 g 6.41 mmol) prepared above and hexafluoroacetone trihydrate (2.86 g 13 mmol). The mixture was heated to gently reflux at 100° C. overnight. EtOAc is added and the mixture was filtered. Solvent was evaporated under reduced pressure. The residue was recrystallized in THF and hexanes to afford the title compound as a white solid. (1.68 g). 1H NMR δ0.95 (t, 3H), 1.40 (m, 2H), 1.6 (m, 2H), 3.20 (t, 2H), 7.3 (s, 1H); ESIMS: m/z 323 (M+H).
