실험 절차
TFA (1 mL) was added to tert-butyl 3-fluoro-4-(2-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)thieno[3,2-b]pyridin-7-yloxy)phenylcarbamate (229) (105 mg, 0.23 mmol) and the mixture was stirred for 1 h at room temperature. The solution was concentrated under reduced pressure, the residue co-distilled with MeCN, redissolved in MeOH and purified by preparative HPLC (gradient 40% to 95% MeOH in water, 45 min) giving 230 (50 mg, 0.1 mmol, 48% yield) as a white solid. MS (m/z): (M+1) 356.1 (100%).
