実験手順

N-[5-(5-amino-6-chloropyridin-3-yl)-4-methyl-1,3-thiazol-2-yl]acetamide (30 mg, 0.11 mmol), benzaldehyde (0.016 mL, 0.16 mmol) and sodium cyanoborohydride (13 mg, 0.21 mmol) were mixed in NMP (0.9 mL) and acetic acid (0.1 mL). Chlorotrimethylsilane (0.04 mL, 0.32 mmol) was added and the mixture was stirred overnight. The reaction product was purified by preparative HPLC (Method A) to give the title product (retention time 9.73 minutes; 19 mg); 1H NMR Spectrum: (DMSOd6) 12.13 (1H, s); 7.60 (1H, d); 7.38-7.30 (4H, m); 7.22 (1H, t); 6.80 (1H, d); 6.67 (1H, s); 4.47 (2H, s); 2.12 (3H, s); 2.03 (3H, s); Mass Spectrum: M+H+ 373 and 375.
