| titleOfInvention | Process for preparing antifolate 4-hydroxypyrrolo 2,3-d pyrimidine derivatives |
| abstract | A process for preparing a 4-hydroxypyrrolo[2,3-d]pyrimidine without isolation or purification of intermediate products, of formula <CHEM> wherein R is NHC*H(COOR<1>)CH2CH2COOR<1> or OR<1>; R<1> is H or a carboxyl protecting group; the configuration about the carbon atom designated * is L; n is 0 or 1; and A is an aryl group which may be substituted; or a salt thereof, which comprises (a) halogenating a compound of the formula <CHEM> wherein R, R<1>, A and * are as defined above; j is 0 or 1; (b) reacting 2,4-diamino-6-hydroxypyrimidine, or a salt thereof, with the reaction product from step (a), in the presence of a polar solvent; (c) optionally hydrolyzing the reaction product of step (b) when R of said reaction product is NHC*H(COOR<1>)CH2CH2COOR<1> and R<1> is a carboxyl protecting group; and (d) optionally salifying the reaction product of step (b), when R of said reaction product is NHC*H(COOR<1>)CH2CH2COOR<1> and R<1> is H, or of step (c). |
