Synthetic example 1

[0128] Synthesis Example 1: Synthesis of Compound 1

[0129]

[0130]1.084 g (4.330 mmol) of compound B-1 was added and stirred to 50 g of dichloromethane. Set the ice bath (icebath) to make it 0°C, then add 0.830 g (4.330 mmol) of N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (N-( 3-Dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride) (EDC-HCl), stirred for 15 minutes. Add a small amount of dimethylformamide, 0.141g (1.155mmol) of 4-dimethylaminopyridine, add 0.737g (1.443mmol) of compound A-1, react at 0°C for 2 hours, and react overnight at room temperature ). Further add 100 ml of dichloromethane and 50 ml of dichloromethane for extraction, and pass the organic layer through Na 2 SO 4 The water was removed and the solvent was removed under reduced pressure. Then, the precipitate was separated by column chromatography (eluent-dichloromethane:methanol). As a result, the title compound 1 (0.422 g, 0.433 mmol) was obtained in a yield of 30%.

[0134] 1.084 g (4.330 mmol) of compound B-1 was added and stirred to 100 g of dichloromethane. Set the ice bath (icebath) to make it 0°C, then add 0.830g (4.330mmol) of N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (EDC-HCl ), and stirred for 15 minutes. Add a small amount of dimethylformamide, 0.141g (1.155mmol) of 4-dimethylaminopyridine, add 2.211g (4.330mmol) of compound A-1, react at 0°C for 2 hours, and react overnight at room temperature ). Further add 100ml of dichloromethane, 50g of dichloromethane and extract, and make the organic layer pass through Na 2 SO 4 The water was removed and the solvent was removed under reduced pressure. Then, the precipitate was separated by column chromatography (eluent-dichloromethane:methanol). As a result, the title compound 2 (0.804 g, 1.083 mmol) was obtained in a yield of 25%.

Synthetic example 3

[0136] Synthesis Example 3: Synthesis of Compound 3

[0137]

[0138] In synthesis example 1, it synthesize|combined by the method similar to synthesis example 1 except having used the compound B-2 of 1.205g (4.33 mmol) instead of compound B-1. As a result, the title compound 3 (0.670 g, 0.650 mmol) was obtained in a yield of 45%.
