5. 1H and 13C spectra were recorded either on a G.E. QE-300 or a Brucker WH-400 Instrument. Mass spectra were determined on a VG-7035. The 1H spectrum of 5 (CHCl3) at 400 MHz exhibited resonances at (ppm) 7.533 (1H, d), 2.052 (1H, q), 1.153 (3H, d), 1.130 (9H, s), 0.929 (9H, m), and 0.563, (6H, m); q = quintet.
