SYNTHESIS OF 2-t-BUTYL-5-HYDROXYPYRIMIDINE VIA HYDROLYSIS OF 2-t-BUTYL-5-HALOPYRIMIDINES
Pews, Richard Garth
, p. 109 - 114 (2007/10/02)
The hydrolysis of 2-t-butyl-5-halopyrimidine (halogen = bromine or chlorine) with sodium methoxide in methanol yields 2-t-butyl-5-hydroxypyrimidine.The side reaction product, 2-t-butylpyrimidine, is substantially reduced, especially in the case of the bromo derivative, with catalytic amounts of elemental sulfur.

Nucleophilic heteroaromatic substitution-XXIV. Kinetics of piperidinodechlorination of 2- and 6- alkyl-4-chloropyrimidines in ethanol and toluene-evidence for a steric hindrance to solvation of the aza-group
Calligaris,Linda,Marino
, p. 813 - 816 (2007/10/07)
The rate constants for the reaction of 2- and 6-alkyl-4-chloropyrimidines with piperidine in toluene and ethanol have been determined at 30.0°. The reactivity ratio kMe/kt-Bu increases considerably in passing from the reaction of 6-alkyl-4-chloropyrimidines in toluene (1.62) to the reaction of 2-alkyl-4-chloropyrimidines in ethanol (17.3). This remarkable increase (over a factor of ten) is ascribed to a steric hindrance to solvation of the aza-groups caused by the bulkier substituent.
