실험 절차
A mixture of t-butyl 4-(5-formylthiazol-2-yl)piperidine-1-carboxylate (250 mg, 0.84 mmol, 1 eq) and 3,3-dimethylbutan-1-amine (94 mg, 0.93 mmol, 1.1 eq) was stirred with molecular sieves at RT for 18 hr. After filtration, the excess solvent was concentrated in vacuo to give (z)-tert-butyl 4-(5-((3,3-dimethylbutylimino)methyl)thiazol-2-yl)piperidine-1-carboxylate (290 mg, 90% yield) with consistent 1H-NMR data. 1H NMR (CDCl3) δ 8.37 (s, 1H), 7.94 (s, 1H), 4.00 (m, 2H), 3.53 (t, J=8.1 Hz, 2H), 2.87 (m, 2H), 2.02 (m, 2H), 1.61-1.46 (m, 5H), 1.47 (s, 9H), 0.94 (s, 9H) ppm.
