실험 절차

A solution of ethyl (3-methoxy-4-nitrobenzyl)methylphosphinate (Compound 216D, 0.500 g, 1.83 mmol) in 37% HCl (5.00 mL) was stirred at 100° C. for 6 hours. The reaction mixture was concentrated under reduced pressure to yield the desired product as a yellow foam, 457.2 mg (102% yield). This material was used in successive reactions without any further purification. 1H NMR (CDCl3, 400 MHz): δ=1.41 (d, J=13.89 Hz, 3 H), 3.13 (d, J=16.42 Hz, 2 H), 3.97 (s, 3 H), 6.89 (d, J=8.08 Hz, 1 H), 7.02 (s, 1 H), 7.82 (d, J=8.34 Hz, 1 H). MS (ES+): m/z 246.05 [MH+] (TOF, polar).
