Procedure
The 2-acetyl-7-chloro-4H,9H-naphtho [2,3-b]furan-4,9-dione 3-2 (R1=Cl, R3=CH3, R7=H) was obtained according to the procedure described in example 13 by using 2-ethyl-7-chloro-4H,9H-naphtho[2,3-b]furan-4,9-dione 1-3 (R1=C1, R4=CH3) as starting materials with yield of 30%. 1H NMR (in CDCl3) δ 2.67 (s, 3H), 7.61 (s, 1H), 7.74-7.78 (m, 1H), 8.17-8.23 (m, 2H).
