We report the results of searches for B{sup +}{yields}J/{psi}{eta}{sup '}K{sup +} and B{sup 0}{yields}J/{psi}{eta}{sup '}K{sub S}{sup 0} decays, using a sample of 388x10{sup 6} BB pairs collected with the Belle detector at the {upsilon}(4S) resonance. No statistically significant signal is found for either of the two decay modes and upper limits for the branching fractions are determined to be B(B{sup +}{yields}J/{psi}{eta}{sup '}K{sup +})<8.8x10{sup -5} and B(B{sup 0}{yields}J/{psi}{eta}{sup '}K{sub S}{sup 0})<2.5x10{sup -5} at 90% confidence level.
