Reaction Steps

DMAP (0.03 mmol) and diisopropylethylamine (DPEA) (0.5 mmol) are added to a solution of 2-hydroxyethyl-2-[1-phenyl-2-methyl-5-(4-methylsulphonylphenyl)-1H-pyrrol-3-yl)acetate in DCM (10 ml), at 0° C., MsCl (0.6 mmol) is added and it is stirred for 3 h, at RT. Then H2O is added (5 ml) and it is stirred for 1 h, the phases are separated and the organic phase is washed with NaHCO3 and then with H2O. It is dried and concentrated. The raw product is purified by chromatography (silica; hexane/EtOAc). Oil, yield 76%. 1H NMR 200 MHz (CDCl3) δ (ppm): 2.05 (s, 3H), 2.96 (s, 6H), 3.50 (s, 2H), 4.13-4.33 (m, 4H), 6.51 (s, 1H), 7.08-7.14 (m, 4H), 7.37-7.41 (m, 3H), 7.62 (d, 2H, J=8.6). MS-ESI: m/z 515 (M+Na+).
