Reaction Steps

2-(2,2-Dimethyl-5-oxo-[1,3]dioxolan-4-ylidene)-N-(4-fluoro-2-methylsulfanyl-benzyl)-N-methyl-acetamide was reacted with paraformaldehyde and 2-morpholin-4-yl-ethylamine as described in Method 44B to give the title compound as a white solid (0.032 g, 76% yield). 1HNMR (300 MHz, CDCl3) δ: 7.07 (1H, dd, J=9.52, 6.23 Hz), 6.92 (1H, dd, J=9.52, 2.56 Hz), 6.82 (1H, td, J=8.06, 2.57 Hz), 4.61 (2H, s), 4.27 (2H, s), 3.95–3.90 (8H, m), 3.76–3.72 (2H, m), 3.39 (2H, t, J=5.85 Hz), 2.97 (3H, s), 2.47 (3H, s).
