al were prepared, and equilibrium constants for their formation from formaldehyde and allopurinol, glutethimide, or phenobarbital were calculated. The N-hydroxymethyl derivatives had higher water solubilities and faster dissolution rates than the parent drugs, and they appear to be potentially useful as prodrugs.
