Method for producing a precursor of pitavastatin calcium |
| abstract |
PROBLEM TO BE SOLVED: To provide a precursor compound of pitavastatin calcium which is excellent in safety and cost and has a high yield and high selectivity under mild conditions. The compound of formula 1 is reacted with a compound of formula 3 in the presence of an alkali metal salt selected from alkali metal carbonates, alkali metal acetates or alkali metal propionates. A method for producing a precursor compound of pitavastatin calcium. [Chemical 1] (Wherein R 1 is a C 1 -C 4 alkyl group, and R 2 is an aryl, aralkyl, or alkyl group) [Selection figure] None |
