Stage #1: at 20℃; for 2 h;
Stage #2: With xylene In methanol at 90 - 120℃; for 16 h; Inert atmosphere
Benzyl 2-amino-2-(hydroxyimino)-1,1-dimethylethylcarbamate (2.0 g, 8.0 mmol) was dissolved in 30 mL MeOH, dimethyl acetylenedicarboxylate (DMAD, 1.1 mL, 9.0 mmol) was added slowly. The mixture was stirred for 2 h at room temperature, and then concentrated under reduced pressure to give a white oil. The mixture of the oil and 80 mL xylene was stirred at 90 °C for 2 h and 120 °C for 2 h, then refluxed for 12 h under nitrogen, concentrated to yield the crude product. The crude product was recrystallized with 2 mL MeOH and 10 mL tert-butyl methyl ether to afford 5 as a yellow solid (1.7 g, 58 percent): 1H-NMR (DMSO-d6) δ: 7.35 (m, 5H), 5.00 (s, 2H), 3.83 (s, 3H), 1.48 (s, 6H); ESI-MS m/z 360 (M), 384 (M+Na) +.
