A process for preparing a compound of the formula
wherein R1, m, o and p are described below, which comprises adding a base of the formula
wherein R2, R3 and R4 are as described below, to a solution comprising a compound of the formula
wherein R1, m, o and p are as described below, and a halonitromethane of the formula O2NCH2X, wherein X is a halogen atom dissolved in a non-aqueous inert solvent. The compounds of formula III are useful as intermediates in the syntheses of azabicyclo quinoline carboxylic acids, and their pharmaceutically acceptable salts and prodrugs, having antibacterial activity. This invention also relates to the base of formula IV wherein each R2 is butyl, R3 is hydrogen and each R4 is t-butyl.
