After that, remove the water bath and stir for 30 minutes. This was filtered under reduced pressure, the insoluble matter was washed with 500 ml of ether, the washing liquid was combined with the washing liquid, and the mixture was dried over anhydrous sodium sulfate. After removing the solvent, distillation was performed to obtain 3-nidradopropanolxo9. sg (yield 827%) was obtained.
