Hope this helps

And the translation for the preparation

Thank you so much sir..

sir, let me ask, what do you mean by 10 mL of dry acetone??

Dear Benhur, dry acetone means that the water has been removed from the acetone before its been used as solvent for the title reaction. If water or traces of are present there will be a competition reaction between the water and the aldheyde for the nucleophile...(see attached file)

You can see methods of drying solvents on : J. Org. Chem. 2010, 75, 8351–835

Nice topic. Good luck on your thesis!
