Participants

Reaction Steps

2-(2,2-Dimethyl-5-oxo-[1,3]dioxolan-4-ylidene)-N-(4-fluoro-2-methanesulfinyl-benzyl)-N-methoxy-acetamide was reacted with methanol using the procedure described for the synthesis of compound 90-C to yield 3-[(4-fluoro-2-methanesulfinyl-benzyl)-methoxy-carbamoyl]-2-hydroxy-acrylic acid methyl ester as a white sticky solid (0.1020 g, 100% yield). This crude was reacted with paraformaldehyde and 4-amino-butyric acid using the procedure described for Compound 810 to give the title compound as an orange solid (0.0360 g, 64% yield). 1HNMR (300 MHz, CDCl3) δ: 7.75 (1H, dd, J=8.05, 2.56 Hz), 7.48 (1H, dd, J=8.42, 4.76 Hz), 7.21 (1H, td, J=8.05, 2.56 Hz), 4.96 (2H, q), 4.19 (2H, s), 3.78 (3H, s), 3.58 (2H, td, J=6.95, 1.83 Hz), 2.82 (3H, s), 2.39 (2H, t, J=6.95 Hz), 1.97–1.92 (2H, m).
