LAH works as a sharm, disolve 200g(0,88mol) of the ester in dry THF or ether, then add 20g(0,5mol) af LAH (app 10% to much)let it stir to the nex day. Add 30% NaOH(aq) until no more H2 formation (stir and take your time, it take some time for the leftowers to react, don't ad to muc at the time) Then ad some MaSO4 filter off, wash the filtercake and ewaporate. Yeald over 90%.
Iff you use the acid instead of the ester use 25% more LAH. And for those who think they can cut down on the LAH in the red, of the acid DON'T make the Na salt of the acid, it wont disolve, only the Li salt works.
I doo feal sorry for you Mountain_Girl, you have made a dam hard work here.
