Logarithmic Integral and convergence

    If p(n) is the n-th prime, p(n)# is the primorial of p(n) and phi(x) is the Euler totient, I currently believe that the logarithmic integral of p(n)^2

      If p(n) is the n-th prime, p(n)# is the primorial of p(n) and phi(x) is the Euler totient, I currently believe that the logarithmic integral of p(n)^2 converges to p(n)^2*phi(p(n)#)/p(n)#. But is there any well-known proof to vindicate this?
      WTIA
