Have a nice day!
Hi, I am a master's student and i have almost no experience with chemical reactions.
![Sad :(](https://www.chemicalforums.com/Smileys/classic/sad.gif)
I have a compound that has a functional group of carboxylic acid, and this group must be changed to primary alcohol. My strategy have been:
Carboxilic acid pass to methyl ester
and methyl ester pass to Primary alcohol
But I have not had success with the reaction

.
My system is buck under nitrogen atmosphere, use 3 equivalent of hydride, and the solvent is anhidrous ether, all at a reflux for 7 hours.
I've tried increasing the time, putting more hydride, but I can´t consume my whole substrate and the yield is minimal.
Someone will experience about the best temperature and order of addition of reactants?

It would be better if I use tetrahydrofuran or anhydrous ether?
