実験手順
Add 2-(pyridin-2-yloxy)ethylamine (500 mg, 3.62 mmol) to a solution of 2-thioacetyl-isoindole-1,3-dione (743 mg, 3.62 mmol) in CHCl3 (18 mL) at 0° C. After stirring for 15 minutes, concentrate the solution, redissolve in ethyl acetate (25 mL), filter, and concentrate again. Flash chromatography (SiO2, 1:1 EtOAc/Hex) gives N-(2-(pyridin-2-yloxy)ethyl)thioacetamide (350 mg, 49%) as a beige/pink solid. 1H NMR (CDCl3) δ 8.79 (br s, 1H), 8.10-8.08 (m, 1H), 7.58-7.65 (m, 1H), 6.92-7.00 (m, 1H), 6.76-6.82 (m, 1H), 4.57-4.65 (m, 2H), 3.98-4.05 (m, 2H), 2.56 (s, 3H).
