実験手順

46-2 (0.21 g, 0.73 mmol) was treated with neat trifluoroacetic acid for 20 minutes and then the trifluoroacetic acid was evaporated off. This residue and 35-1 (0.17 g, 0.73 mmol) and triethylamine (0.37 g, 3.67 mmol) were heated at 150° C. for 3 hours in n-butanol. Upon cooling the precipitate was filtered off, washed with n-butanol and ethyl ether and then dried to afford 46-3. Hi-Res MS: calc: 386.1758 found: 386.1754. 1H-NMR (CD3OD): 8.36(s, 1H); 7.99(s, 1H); 6.14(s, 1H); 4.40(d, 2H); 3.98(m, 1H); 2.94(t, 2H); 2.10(complex, 3H); 1.77(d, 2H); 1.22(m, 2H); 1.13(d, 6H).
