-Select the optimal synthesis route and conduct a small-scale test (0.1L~10L)
-Optimize reaction conditions (temperature, catalyst, etc.) -The purity and yield of the target compound meet the standard
-HPLC/GC purity testing, GC/HPLC-MS, NMR structure confirmation

-Conduct kilogram scale amplification experiments (10L~50L)
-Research on by-product control, separation and purification, solvent recovery, etc -Calculate ton level production costs and evaluate industrialization feasibility

-Production scale: 200L~3000L reaction kettle
-GMP_LIKE level production
-Ensure consistency of all batches of products (batch differences<1%)
-Conduct quality control testing (HPLC, GC, MS, etc.)
