A method for preparing an intermediate for the synthesis of etoposide phosphate and etoposide |
| abstract |
The present invention relates to a novel process for the preparation of a protected 4'-demethyl-4-epipodophyllotoxin-4'-phosphate of formula (II) wherein R3 is an arylmethyl group of the formula (I) by means of a di (arylmethyl) ) is reacted with phosphite, a tetrahalomethane, a tertiary amine, and an acylating catalyst. ŕ |
