在小试过程中，我们在进行step 3的反应时，发现杂质较多。但是后面仍

During the small test, when we performed the step 3 reaction, we found more impurities. However, the reaction can still be continued and the target product is produced, but the yield is low and there are many impurities. <br>After the completion of the first small test, we found it necessary to optimize the small test when doing the enlarged step 3. Now the first optimization of the small test has been completed, and the overall yield is 8.2%. Taking into account the subsequent scale-up production, we will continue to optimize the small test in the future, and provide you with a new small test product detection map and production schedule, please check!

During the small test, we found more impurities when we reacted to step 3. However, the later can continue to react and generate the target product, but the yield is low and the impurities are more.<br>After the first small test was completed, we found it necessary to optimize the small test in the enlarged step 3, and now we have completed the first optimization of the small test, with an overall yield of 8.2%. Considering the subsequent amplification of production, we will continue to optimize the small test, and provide you with new small test product test map and production schedule, please check!

In the process of small scale test, we found that there were many impurities in the reaction of step 3. However, the reaction can continue to form the target product, but the yield is low and there are many impurities.<br>We found that it is necessary to optimize the pilot test when we did the enlarged step 3 after the first pilot test. Now we have completed the first optimization of the small test, and the overall yield is 8.2%. Considering the follow-up scale-up production, we will continue to optimize the pilot test, and provide you with a new test product test atlas and production schedule, please check!<br>
