実験手順
The product was made by reducing ethyl 4-nitrocinnamate (110.6 g, 0.5 mol) with 10% palladium on Carbon (4.0 g) in 95% ethanol (2 L) in the presence of ammonium formate (126 g) to afford ethyl 3-(4-aminophenyl)propionate which was sulfonated with methanesulfonyl chloride in CH2Cl2 in the presence of pyridine to produce 102 g (75.2%) of N-[4-(ethoxycarbonylethyl)phenyl]methanesulfonamide.
