実験手順
To a 200 mL round bottomed flask with a stirring bar and a drying tube was added N,N-dimethyl 4-(1,1-dimethylethoxycarbonyl)amino-3-methyphenoxyacetamide (1.00 g, 3.24 mmol) and trifluoroacetic acid (20 mL). This solution was stirred at ambient temperature 48 h. The trifluoroacetic acid was removed in vacuo and the residue was dissolved in 200 mL of EtOAc. This solution was washed with NaHCO3 solution and brine. Drying (MgSO4), filtration and removal of the solvent in vacuo gave 0.493 g (73% yield) of N,N-dimethyl 4-amino-3-methylphenoxyacetamide as white crystals. 1H NMR (CDCl3): d 2.15 (s, 3H), 2.97 (s, 3H), 3.08 (s, 3H), 3.27 (br s, 2H), 4.59 (s, 2H), 6.71 (m, 3H). ##STR52## N,N-Dimethyl-2-(4-amino-3-methylphenoxy)ethylamine (5-4)
