Here is a downstream synthesis route of the compound 74137-36-3, Product Details of 74137-36-3
The Bl (3.34g, 10 mmol) was added vial, the injection of THF dried, placed in a dry ice – acetone bath cooling, -78 ° C was added dropwise n-BuLi (1 lmmol, 2.5M) solution, stirring was continued for 3 hours and then triisopropyl borate (2.07g, 11 mmol) added to the bottle, slowly brought to room temperature and stirred overnight. After completion of the reaction, dilute HC1 solution was dropwise jerk, and extracted with methylene chloride, the organic layer was dried, solvent was removed, dichloromethane and petroleum ether (60-90) was washed with a mixture of beating to give D-1 (2.57g, y = 86percent),
