Abstract

Objective To synthesis the new anti-osteoporotic risedronate sodium. Methods Nicotinic acid was used as raw material, by esterification, condensation, Willgerodt reaction and hydrolysis steps to get the key intermediate 3-pyridine acetic acid hydrochloride.Then 3-pyridine acetic acid hydrochloride and phosphorous acid reacted to obtain the risedronate sodium. Results The reaction time, reaction conditions and the yield of Willgerodt reaction were explored. The synthetic route was optimized and the total yield of the reactions was increased. Conclusion This synthetic route of risedronate sodium could be applied to industrial production.
- risedronate sodium,
- anti-osteoporotic,
- chemical synthesis
