Abstract
PURPOSE: To prepare the titled compound useful as a remedy for obnubilation caused by brain lesion, economically, in an industrial scale, by condensing cytidine- 5'-phosphate with a metal salt of phosphorylcholine halide in the presence of a specific amount of thionyl chloride.
CONSTITUTION: The objective compound can be obtained by condensing (A) cytidine-5'-phosphate with (B) a metal salt of phosphorylcholine halide (e.g. calcium salt of phosphorylcholine chloride) in the presence of ≥1mol, pref. 2W4mol, based on 1mol of the component B, of thionyl chloride, pref. in an organic solvent such as dimethylformamide, etc., e.g. at 0W40°C for 1hr.
EFFECT: The objective compound can be prepared with a simple process, in high yield, without using expensive reagents.
