Abstract

A procedure for preparing quinazoline derivatives represented by the formula: **(See formula)** where R1 and R2 are, individually, a hydrogen atom, a lower alcohol group, a lower alkoxy group, a nitro group, a trifluoromethyl group, a lower alcoholylthio group, a lower alcohol sulfonyl group or a halogen atom; R3 is a group of the formula (see formula) (where R4 is a hydrogen atom, a lower alcohol group, a lower alkoxy group, a trifluoromethyl group or a halogen atom), a naphthyl group, a lower cycloalkyl group, a group lower cycloalkenyl, a pyridyl group, a pyrrolyl group, a thienyl group or a furyl group; R is a lower cycloalkyl group, a trihalomethyl group, a lower alkoxy group, a lower alcoholylthio group, a lower alkanoyloxy group, or a group of the formula (see formula) (where R5 and R6 are, individually, a lower alcoholic group, with such that R5 and R6 can form, together with the adjacent nitrogen atom, a 5- or 6-membered heterocyclic ring, unsubstituted or optionally substituted, which may further contain a nitrogen, oxygen or sulfur atom); and n is an integer from 1 to 3; which procedure comprises: reacting a compound represented by the formula: **(See formula)** where R1, R2, R and n are as defined above, with a compound of the formula: R3 - CHO (V) where R3 is as defined above.
