4-Methylmorpholine → HCID 59363835, compound

Participants

Reaction Steps

To a mixture of 2-(2,4-Difluoro-phenoxy)-2-(4-methanesulfonyl-phenyl)-propionic acid (0.110 g, 0.22 mmol), (2-Amino-5-chloro-thiazol-4-yl)-acetic acid methyl ester (0.071 g, 0.32 mmol), HOBt (0.052 g, 0.38 mmol), and EDCI (0.074 g, 0.38 mmol) in methylene dichloride (10 ml) was added N-methylmorpholine (0.039 g, 0.38 mmol). The resulting mixture was stirred at room temperature for overnight followed by dilution with 10 ml methylene dichloride. The reaction mixture was poured onto water (20 ml), and organic layer separated, washed with water (2×20 ml), brine (20 ml), dried over sodium sulfate and solvent evaporated to get residue which was purified by preparative TLC using 50% ethyl acetate in hexane as mobile. To give desired compound (0.30 g). 1H NMR (400 MHz, CDCl3): δ 1.45 (t, J=7.2 Hz, 3H), 1.93 (s, 3H), 3.14 (s, 3H), 3.77 (d, J=2.8 Hz, 1H), 4.26 (q, J=7.2 Hz, 1H), 6.69-6.77 (m, 2H), 6.96-7.02 (m, 1H), 7.89 (d, J=8.4 Hz, 2H), 8.07 (d, J=8.4 Hz, 1H); MS (D) m/z: 559.00 (M+1).
