Method of preparing a polymorph of terfenadine |
| abstract |
The invention relates to a method for preparing HMP terfenadine comprising the steps of reacting terfenadone free-base with sodium borohydride to yield mixed polymorph terfenadine and crystallizing said mixed polymorph terfenadine from a seeded ester or ketone solvent system to yield substantially pure HMP terfenadine. |
