Procedure
A mixture of 6 (9.8 g, 0.024 mol), AgNO3 (8.8 g, 0.052 mol), EtOH (100 mL) and H2O (25 mL) was heated on a steam bath for 1 hour. The yellow solid was filtered and the solution concentrated to dryness. The residue was treated with H2O and extracted with CHCl3 (3×). The organic layer was dried, filtered and concentrated to dryness. Distillation of the resulting oil at 105°-135° C. at 0.5 mm gave 3.0 g (48%) of 3; 1H NMR (CDCl3) 1.45 δ (3H, t, J=7), 4.4 (2H, q, J=7, 8.6 (1H, d, J=2),/8.9 (1H, d, J=2) and 10.1 (1H, s).
