Embodiment
[0458] Examples are given below to further specifically illustrate the present invention. The materials, reagents, substance amounts, their ratios, operations, etc. shown in the following examples can be appropriately changed without departing from the spirit of the present invention. Therefore, the scope of the present invention is not limited to the following specific examples.
Synthetic example 1
[0459] [Synthesis Example 1] Synthesis of Compound A-5
[0460] [Chemical formula 52]
[0461]
[0462] To a solution obtained by mixing 50 g of diethylaminoacetanilide and 265 g of isopropanol, 177 g of 35% hydrochloric acid was added dropwise, and the mixture was heated and stirred at an internal temperature of 60°C for 24 hours. After the reaction was completed, after cooling to 0°C, the pH was increased to 9.5 using a 50% NaOH aqueous solution, and then 600 ml of ethyl acetate and 400 ml of water were added to extract the organic layer. The organic layer was further washed with saturated brine, dried and concentrated using magnesium sulfate, and then purified by silica gel column chromatography (hexane / ethyl acetate=4 / 1) to obtain 35.1 g (88 %) Intermediate 1.
[0463] To a solution obtained by mixing 4.5 g of ferrocene acetic acid and 33.2 g of dichloromethane, 2.3 g of oxalyl chloride was added, and the mixture was heated and stirred at 30° C. for 1 hour to prepare a mixed so...
Synthetic example 2
[0468] [Synthesis Example 2] Synthesis of Compound A-38
[0469] [Chemical formula 53]
[0470]
[0471] After completely dissolving 60 g of tert-butylhydrazine hydrochloride in 240 ml of methanol, 40 g of sodium acetate and 31.3 g of ethyl acetoacetate were added, and the mixture was stirred at room temperature for 1 hour. Then, it was heated to reflux for 6 hours. After the completion of the reaction, the precipitate was filtered after cooling to room temperature, and the obtained filtrate was concentrated to an extent not completely dried, 80 ml of saturated brine was added, and extraction was performed 3 times with 200 ml of chloroform. After concentrating the obtained chloroform layer, it was purified by silica gel column chromatography (hexane / ethyl acetate=2 / 1), thereby obtaining 33.9 g (91%) of Intermediate 3.
[0472] After 7.7 g of intermediate 3 and 7.3 g of dimethyl squarate were completely dissolved in 85 ml of methanol, 7.1 g of potassium carbonate was added, and the ...
