실험 절차

EDC (54 mg, 0.28 mmol) was added to a suspension of (E)-3-(5-methyl-4-oxo-1,2,3,4,5,6-hexahydropyrido[2,3-b][1,5]diazocin-8-yl)acrylic acid hydrochloride (70 mg, 0.23 mmol), HOBt (34 mg, 0.25 mmol), N-methyl(3-methylbenzo[b]thiophen-2-yl)methanamine (48 mg, 0.25 mmol) and (i-Pr)2EtN (0.20 mL, 1.2 mmol) in 5 mL of DME:propionitrile (4:1). The mixture was allowed to stir for 1 h at 40° C. The mixture was cooled to room temperature and diluted with ethyl acetate (40 mL) and washed with water (50 mL) and NaHCO3 (50 mL), dried over MgSO4 and dried under high vacuum. The solid was then subjected to purification on Prep HPLC to obtain the product as a fluffy white solid. Yield 54 mg (54%); 1H NMR (400 MHz, CDCl3) δ10.41 (bs, 1H), 8.08 (s, 1H), 7.79-7.68 (m, 3H), 7.59 (d, J=15.2 Hz, 1H), 7.40 (m, 2H), 6.95-6.86 (m, 1H), 4.96 (s, 2H), 4.72 (bs, 2H), 3.90 (s, 2H), 3.15 (m, 5H), 2.84 (s, 3H), 2.46 (s, 3H); ESI MS m/z 435 [C24H26N4O2S+H]+
