Scalable non-aqueous process to prepare water soluble 3-amino-pentan-1,5- diol

The development of a nonaqueous process for the synthesis of 3-amino-pentan-1,5-diol is described. Beginning with dimethyl acetone-1,3-dicarboxylate, a telescoped sequence of reductive amination, Boc protection, sodium borohydride reduction, and acidic resin-mediated deprotection generates the title compound. The key to this efficient process is the telescoped deprotection, purification and nonaqueous isolation of the 3-amino-pentan-1,5- diol. The process involves four optimized chemical reactions using two solvents in 89% overall yield and 97-98 area % purity.

NOVEL PROCESS FOR THE PREPARATION OF 3-AMINO-PENTAN-1,5-DIOL

The present invention provides a novel method for preparing a key intermediate, 3-amino-pentan-1,5-diol (2), which is useful for the preparation of 6-(2,4-difluorophenoxy)-2-[3-hydroxy-1-(2-hydroxyethyl)-propylamino]-8-methyl-8H-pyrido[2,3-d]pyrimidine-7-one (1) a MAP-kinase inhibitor useful in the treatment of rheumatoid arthritis.
