5. Melting points were obtained on a Thomas Hoover Unimelt and are corrected. Infrared data were recorded on a Beckman IR 10 spectrophotometer, and values are expressed in cm−1. Nmr data were recorded on a Varian Associates Model A-60 A spectrophotometer using 3-(trimethylsilyl)-1-propanesulfonic acid sodium salt as internal standard and deuterium oxide as solvent. All chemical shifts are in ppm (δ). Microanalyses were conducted by Midwest Microlab, Inc., Indianapolis, Ind.
