Examples
Embodiment 1
[0088] Example 1: Benzyl-4-(2-(methylcarbamoyl)pyridin-4-oxyl)phenylcarbamate (SH-007)
[0089]
[0090] Weigh 0.710g (0.003 mol) of 4-(4-aminophenoxy)-N-methylpicolinamide into a 100 ml three-neck round bottom flask, add 20 ml of dichloromethane and stir to dissolve, then add 0.4 ml of triethyl amine, under ice bath, slowly add 0.4ml of benzyl chloroformate dropwise, after the dropwise addition, react at room temperature for 1 h, wash with water, extract the organic layer, and separate by column chromatography (eluent: petroleum ether / ethyl acetate = 1: 1), a white solid was obtained. Melting point: 119.2-120.2°C.
[0091] 1 H NMR (CDCl 3 ) δ (ppm): 8.37 ~ 8.35 (d, 1H, pyridine- H ), 8.01 (s, 1H, N H CO), 7.70 (s, 1H, pyridine- H ), 7.47 ~ 7.34 (m, 7H, Ar- H, ), 7.05 ~ 7.02 (d, 2H, Ar- H ), 6.95 ~ 6.92 (m, 1H, pyridine- H ), 6.79 (s, 1H, N H CO), 5.22 (s, 2H, C H 2 ), 3.01 ~ 3.00 (d, 3H, CH 3 ).
