contents We compute $\mathrm{Ext}^{1}_B(χ_1,χ_2)$ between two characters $χ_1,χ_2$ of a Borel subgroup $B$ of a split reductive group $G$ over a finite field $\mathbb{F}_q,$ and make an application to the calculation of $\mathrm{Ext}^1_G(π_1,π_2)$ between principal series representations $π_1,π_2$ of $G(\mathbb{F}_q).$
