Embodiment 1
[0184] (Example 1) Synthesis of an intermediate (compound 3A) illustrating compound 112
[0185] [Chemical 51]
[0186]
[0187] 6.74 g of compound 1A and 1.52 g of triethylamine were added to 100 ml of dichloromethane at room temperature, and after cooling to an internal temperature below -10°C, 3.08 g of compound 2A in dichloromethane was added dropwise below 0°C. After completion of dripping, it was made to react at 0 degreeC or less for 4 hours. Put 15ml of 1N-HCl at below 15°C, transfer to a separatory funnel, remove the water layer, wash the organic layer with water, neutralize, concentrate under reduced pressure, and purify the obtained residue by column chromatography, then decompose with hexane Analysis (dialysis), filtration, and drying gave an orange-red solid. Structure through MASS, 1 H-NMR and IR spectroscopy to identify.
Embodiment 2
[0188] (Example 2) Synthesis of an intermediate (compound 4A) illustrating compound 112
[0189] [Chemical 52]
[0190]
[0191] 7.57 g of compound 3A, 100 ml of 1N-HCl, and 3.32 g of potassium iodide were added to 100 ml of acetonitrile, heated to an internal temperature of 100° C., and reacted for 1 hour. The reaction solution was cooled to below 0°C, neutralized and washed with water, the organic layer was concentrated under reduced pressure, and the resulting residue was purified by column chromatography to obtain an orange-red solid. Structure through MASS, 1 H-NMR and IR spectroscopy to identify.
Embodiment 3
[0192] (Example 3) Synthesis of Exemplary Compound 112
[0193] [Chemical 53]
[0194]
[0195] 6.72 g of compound 4A and 3.24 g of triethylamine were added to 100 ml of dichloromethane, and after cooling to an internal temperature of 0° C. or lower, a dichloromethane solution of 2.72 g of acryloyl chloride was dropped at 0° C. or lower. After completion of the dropping, the reaction was made at an internal temperature of 0° C. or lower for 4 hours. Put 35ml of 1N-HCl at below 15°C, transfer to a separatory funnel, remove the water layer, wash the organic layer with water, neutralize, concentrate under reduced pressure, and purify the obtained residue by column chromatography, then decompose with hexane analysis, filtration, and drying to obtain an orange-red solid. Structure through MASS, 1 H-NMR and IR spectroscopy to identify.
