Answer to Question #202508 in Organic Chemistry for Arlin Arias

Question #202508

Suppose you were attempting to synthesize 5.0g of lidocaine, using this reacción sequence (and the corresponding purification after each step). If each reaction produces the percent yield given, and each purification step produces only 90% recovery of the desired material, how many grams of each reagent do you need in order to end up with the desired mass?


Reaction 1 (72% yield):

C8H11N + C2H2OCl2 ----> C10H12NOCl + HCl

Reaction 2 (45% yield)

C10H12NOCl + C4H11N ----> C14H22N2O + HCl
