Yield: 45%
Reaction Conditions:
in tetrahydrofuran;ethanol at -70; for 1 h;Inert atmosphere;
Steps:
10.3 Step 3: Synthesis of compound 10-5
Add compound 10-4 (2.0 g, 7.72 mmol), tetrahydrofuran (20 mL), and replace with nitrogen into a three-necked flask.Cool to -70 in ethanol dry ice bath,Then add ethylmagnesium bromide (28mL, 1mol/L) dropwise,React at this temperature for 1h. The reaction was poured into a saturated ammonium chloride solution, extracted with ethyl acetate three times, the organic phases were combined, and silica gel was added to mix the sample, and then purified by a silica gel column to obtain 680 mg of product 10-5, with a yield of 45%.
