HCID 5949302,6-DiacetoxynaphthaleneYield 93%

Procedure

Subsequently, 45 g of the thus obtained 2,6-dihydroxynaphthalene were acetylated with 23 g of acetic acid and 61 g of acetic anhydride in the same manner as in Example 7 to obtain 60.6 g of 2,6-diacetoxynaphthalene of the purity of 99.85% (by DSC) in a yield of 93.0%.
