Embodiment 1
[0074] Example 1.1-(6-(3-amino-1-methyl)indazole)-3,6,6-trimethyl-1,5,6,7-tetrahydroindazol-4-one
[0075] (Compound I-01)
[0076] Add 3,6,6-trimethyl-1,5,6,7-tetrahydroindazol-4-one (0.20 g, 1.1 mmol), dry DMF (15 ml), sodium hydride ( 33 mg, 1.3 mmol), A3 (0.3 g, 1.1 mmol) was added with stirring, and the reaction was heated to 150°C and stirred for 2 hours. After cooling, it was extracted with ethyl acetate, washed with saturated NaCl aqueous solution, and dried over anhydrous magnesium sulfate. Filtration, removal of solvent, separation and purification of the product by silica gel column chromatography, eluting with ethyl acetate / cyclohexane (60:40) to obtain 0.34 g of intermediate, which was dissolved in trifluoroacetic acid (15 ml) at room temperature After stirring for 2 hours, the solvent was removed under reduced pressure, extracted with ethyl acetate, washed with saturated NaCl aqueous solution, and dried over anhydrous magnesium sulfate. Filtration, removal o...

[0077] Example 2.1-(6-(3-amino-1-propenyl)indazole)-3,6,6-trimethyl-1,5,6,7-tetrahydroindazol-4-one
[0078] (Compound I-02)
[0079] Taking intermediate A4 as starting material, synthesize 1-(6-(3-amino-1-propenyl) indazole)-3,6,6-trimethyl-1,5 with the method in Example 1, 6,7-tetrahydroindazol-4-one, yield 54% (two steps); mp (°C) 173-175; 1 HNMR (500MHz, DMSO-D 6 )δ (ppm): 7.71-7.73 (d, 1H), 7.39-7.41 (b, 1H), 7.11-7.13 (d, 1H), 5.75 (m, 1H), 4.95-4.98 (m, 2H), 3.97 (m, 2H), 3.72(s, 2H), 2.64(s, 3H), 2.42(s, 2H), 2.37(s, 2H), 1.07-1.10(s, 6H); MS 350.2(M + +1).
Embodiment 3
[0080] Example 3.1-(6-(3-amino-1-(3-(1-methylcyclohexyl-4-amino)-4-carbamoylphenyl))indazole)-3,6,6-tri Methyl-1,5,6,7-tetrahydroindazol-4-one
[0081] (Compound I-03)
[0082]According to the method of Example 1, the corresponding 1-(6-(1-tert-butoxy Formyl-3-tert-butoxycarboxamido)indazole)-3,6,6-trimethyl-1,5,6,7-tetrahydroindazol-4-one, yield 78%; mp( ° C) 157-159; 1 HNMR (500MHz, DMSO-D 6 )δ (ppm): 7.92-7.94 (b, 1H), 7.69-7.71 (d, 1H), 7.51-7.53 (d, 1H), 6.78-6.80 (m, 1H), 2.66 (s, 3H), 2.44 (s, 2H), 2.35 (s, 2H), 1.08-1.11 (s, 6H); MS 510.3 (M + +1).
[0083] The above product (0.25 g, 0.4 mmol) was dissolved in trifluoroacetic acid (15 mL) to remove tert-butoxyformyl to give the corresponding 1-(6-(1H-3-amino)indazole)-3,6,6 - Trimethyl-1,5,6,7-tetrahydroindazol-4-one 0.1 g, yield 80%. 1-(6-(1H-3-amino)indazole)-3,6,6-trimethyl-1,5,6,7-tetrahydroindazol-4-one (0.1 g, 0.3 mmol ) was dissolved in dry DMF (15 ml), sodium hydride (10 mg, 0.4 mmol) was added, and ...
