Chloromethyl hexanoate (3.18 g, 19.0 mmol) in dichloromethane (6 mL) was added to a suspension of Ziprasidone free base (4.0 g, 9.6 mmol), triethyl amine (4.0 mL, 27 mmol) and 4-dimethylamino pyridine (DMAP, 0.708 g, 5 mmol) in dichloride methane (240 mL) at 25-30° C. The reaction solution was stirred for 24 h at same temperature. The crude mixture was washed with water (100 mL) followed by brine solution (100 mL), upon solvent evaporation under vacuum below 40° C. provided crude title product, Compound 322, which was further purified by silica gel column chromatography. (1.4 g, 27% yield).
