Yield:90204-94-7 700 mg
Reaction Conditions:
with methanol;lithium hydroxide monohydrate at 50; for 1 h;
Steps:
9.2 Step 2: Synthesis of compound 9-2
At room temperature, LiOH (447.57 mg, 18.69 mmol) was added to a MeOH (10 mL) solution of compound9-1 (1.7 g, 9.34 mmol), and the mixture was moved to 50°C reacting for 1 hour. Add the dilute hydrochloric acid solutionequivalent to LiOH to free the target product and spin to dry directly. The residue was purified by flash silica gel columnchromatography (DCM:MeOH=92:8-90:10) to obtain the desired target as a yellow solid product 9-2 (700 mg, 44.85%yield). ESI-MS m/z: 158.15 [M+H]+.
