Embodiment 1
[0087] Example 1 2-methoxy-4-((E)-3-(2-morpholinoethylamino)-3-oxapropenyl)phenyl-farnesylthiosalicylate (I 1 ) preparation
[0088] Preparation of (E)-3-(4-hydroxy-3-methoxyphenyl)-N-(2-morpholinoethyl)acrylamide (5a)
[0089] 2-Morpholinoethylamine (2.03 g, 15.5 mmol) and triethylamine (4.70 g, 46.5 mmol) were dissolved in 20 mL of anhydrous CH 2 Cl 2 In ice bath, slowly dropwise add acetyl ferulic acid chloride (6a, 1.31g, 5.16mmol) in CH 2 Cl 2 Solution 20mL, remove the ice bath after dripping, continue to stir at room temperature, spot the plate until the reaction is complete. Concentrate the reaction solution, dissolve the concentrate in 10 mL of methanol, add 1N NaOH solution, continue to stir at room temperature for 2 hours, adjust the pH to neutral, concentrate to make sand, and pass through the column (PE:AE=1:1~1:4). 1.17 g of a colorless transparent viscous liquid was obtained, with a yield of 74%.

Embodiment 3
[0099] Example 3 2-Methoxy-4-((E)-3-(4-methylpiperazin-1-yl)butoxy)-3-oxapropenyl)phenyl farnesylthio water Salylate (I 3 ) preparation
[0100] Preparation of (E)-4-bromobutyl-3-(3-acetoxy-4-hydroxyphenyl)acrylate (2a)
[0101] Ferulic acid (1a, 5g, 25.8mmol) was dissolved in 50mL of acetone, 1,4-dibromobutane (21.6g, 100mmol), 10mL of Et 3 N, heated at an external temperature of 50°C for 4h. After cooling to room temperature, a large amount of white solid precipitated, filtered, the filtrate was concentrated, and column chromatography [ethyl acetate: petroleum ether (60-90°C) = 1:4 (V:V)] was eluted to obtain a light yellow needle-like solid 6.85g (77%), mp 96-98°C.
