preparation example 1
[0476] Preparation Example 1: Synthesis of Compound A-1
[0477]
[0478] In 6-bromo-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene (40.5g, 151.566mmol), methyl 3-mercaptopropionate (16.6ml, 150mmol) , Pd 2 dba 3 (2.06g, 2.24mmol), Xantphos (4,5-bis(diphenylphosphino)-9,9-dimethylxanthene) (2.6g, 4.49mmol) and DIPEA (52ml, 298.54mmol) were dissolved in two After being dissolved in alkane (1000ml), the mixture was stirred under reflux. When the reaction was completed, the resultant was cooled to room temperature, and stirred after adding NaOtBu (43 g, 450 mmol) thereto. When the reaction was complete, bromoacetaldehyde diethyl acetal (45.1 ml, 299 mmol) and dimethylformamide (DMF) (500 ml) were introduced thereto, and the resultant was stirred. When the reaction was complete, the resultant was cooled to room temperature, and the reaction mass was transferred to a separatory funnel followed by extraction. The resultant was treated with MgSO 4 It was dried, filtered...
preparation example 2
[0480] Preparation Example 2: Synthesis of Compound A-2
[0481]
[0482] After compound A-1 (50.5 g, 150.1 mmol) and polyphosphoric acid (105 ml) were dissolved in monochlorobenzene (MCB) (750 ml), the mixture was stirred under reflux. When the reaction was complete, the resultant was cooled to room temperature, and the reaction mass was transferred to a separatory funnel followed by extraction. The resultant was treated with MgSO 4 It was dried, filtered, concentrated, and purified using column chromatography to obtain compound A-2 (33.01 g, yield 90%).
