Abstract
Improvements made to the subject of main patent No. 407,527 filed on October 11, 1972 by: A method of preparing a pyrido (2,3-d) pyrimidine of formula (A): **(See formula)** in which the dotted line indicates the presence of two additional bonds in the rest Q2-C (2) -N (3) -C (4) -Q1, where Q1 and Q2 are the same or different, bearing the N atom (3) a substituent consisting of a hydrogen atom, and are selected from the class consisting of oxygen and sulfur atoms and the imino group; or else only one of the groups Q1 and Q2 is as defined above, the other being a halogen atom, a hydroxyl group, an optionally substituted amino, thiol or alcoholylthio group, R2, R3 and R4 are the same or different and each one of them may be a hydrogen atom or a lower alcohol group as long as only one of R2, R3 and R4 represents an alcohol group; the remaining two substituents representing from R2, R3 and R4 representing hydrogen atoms; and R1 represents a D-ribityl group; whereby such improvements comprise: (a) reacting a pyrimidine derivative of formula (C) with a compound of formula (D) or an alkali metal salt, such as sodium, acetal or ketal thereof. **(See formula)** in which Q1, Q2, R2 and R4 are as defined above, R3 may be the group R3 and Z represents the group NHR1, where R1 is as defined above, in which case either: (i) X is an hydrogen or halogen atom, or an optionally substituted alkoxy, acetyloxy, hydroxy, alcohol, thiol, or amino group, or (ii) X, taken together with R represents an additional bond when R3 in the compound of the formula (A) represents hydrogen; (b) when X is hydrogen, separate two superfluous labile hydrogen atoms from the intermediate formed; and (c) optionally converting said Q1 and/or Q2 groups, when they are substituents other than the oxygen atom or the hydroxyl group, to a hydroxyl group or an oxygen atom.
