Procaine is a key component of Novocain, an injectable local anesthetic used in dental work and minor surgery. Procaine can be prepared in the presence of H₂SO₄ (indicated above the arrow) by the reaction

                                                                                (H₂SO₄)

                                C₇H₇NO₂ + C₆H₁₅NO   ®  C₁₃H₂₀N₂O₂ + H₂O

If we carried out this reaction using 10.0 g of p-aminobenzoic acid (C₇H₇NO₂) and 10.0 g of 2-diethylaminoethanol (C₆H₁₅NO), and we isolated 15.7 g of procaine (C₁₃H₂0N₂O₂), what was the

Percent yield?

(p-aminobenzoic acid (C₇H₇NO₂): 137.14 g/mol;

2-diethylaminoethanol (C₆H₁₅NO): 117.19 g/mol; procaine (C₁₃H₂₀N₂O): 236.31g/mol).
