METHOD FOR INDUSTRIALLY PRODUCING 2-DEOXY-RIBOSE-1- PHOSPHATE SALT

摘要

PROBLEM TO BE SOLVED: To provide a method for stably producing in high quality a 2-deoxy- ribose-1-phosphate salt important as a raw material for pharmaceutical intermediates through improving its filterability by altering its crystal form. SOLUTION: The method for producing the 2-deoxy-ribose-1-phosphate comprises synthesizing the objective salt of a compound of formula (2) in a non-aqueous solvent by eliminating the 4-chlorobenzoyl groups from a compound of formula (1) or a salt thereof, wherein the charging concentration of the compound of formula (1) or the salt thereof is set so as to enable the compound of formula (2) to be isolated in the form of needle crystal.
