Abstract

122-123'; NMR (CDC13) aliphatic H's 1.82 (m, 4 H), 2.62 (m, 4 H), 3.10 (m, 4 H), 3.82 ppm (m, 4 H); aromatic H's 7.27 (d, J= 8.5 Hz, 1 H), 6.96 (d, J= 2 Hz, 1 H), 6.85 ppm (dd, J= 8, 2 Hz, 1 H). Irradiations at 3.10 ppm result in the sharpening of the d (6.96) and of the dd (6.85). Irradiations at 2.62 ppm result in the sharpening of the d (7.27).
