Reaction Steps
In step 14, compound (20) is reacted in dichloromethane with hydrogen chloride in the form of a diethylether solution under ice-cooling, to convert the 4-diazoacetyl group of compound (20) into 4-chloroacetyl group. Thereby, 1-(3,5-di-O-acetyl-2-deoxy-2-fluoro-β-D-ribofuranosyl)-4-chloroacetyl-5-(dimethylaminomethyleneamino)imidazole [compound (21)] is produced.
