Procedure
2(2,2-Dimethyl-5-oxo-[1,3]dioxolan-4-ylidene)-N-(4-fluoro-2-methylsulfanyl-benzyl)-N-methoxy-acetamide was reacted with methanol to give 3-[(4-fluoro-2-methylsulfanyl-benzyl)-methoxy-carbamoyl]-2-hydroxy-acrylic acid methyl ester as a white sticky solid (0.0807 g, 88% yield). This was then reacted with paraformaldehyde and 4-amino butyric acid following the procedure described for Compound 810 to give the title compound as an orange solid (0.0360 g, 64% yield). 1HNMR (300 MHz, DMSO) δ: 12.10 (1H, bs), 11.35 (1H, bs), 7.30 (1H, m), 7.14 (1H, dd, J=12.44, 2.20 Hz), 6.97 (1H, td, J=8.41, 2.65 Hz), 4.86 (2H, s), 4.18 (2H, s), 3.69 (3H, s), 3.42 (2H, t, J=6.73 Hz), 2.50 (3H, t, J=1.83 Hz), 2.22 (2H, t, J=6.73 Hz), 1.78 (2H, m).
