実験手順

3-Ethoxycarbonyl-5-[N-(tert-butyloxycarbonyl)aminomethyl]isoxazole (Method 73; 500 mg, 1.85 mmol) was dissolved in pyrrolidine (4 ml) and the mixture heated for 3 hours at 85° C. The volatiles were removed by evaporation and the residue was triturated with diethyl ether to give the title compound (432 mg, 79%) as a white solid. NMR (DMSO): 1.38 (s, 9H), 1.85 (m, 4H), 3.50 (t, 2H), 3.62 (t, 2H), 4.29 (d, 2H), 6.47 (1H), 7.53 (s, 1H); m/z 240 (M-C4H8)+.
