If $R$ is a commutative reduced ring, the following are equivalent: 1) the classical quotient ring of $R$ is von Neumann regular; 2) The spectrum of minimal ideals of $R$ is compact in the Zariski topology, and if a finitely generated ideal is contained in a union of minimal primes, it is contained in one of them.
