trans-4-(2-Amino-5-bromo-6-methyl-pyrimidin-4-ylamino)-1-methyl-cyclo-hexa-nol.

Hoffman JE, Cheng H, Rheingold AL, Dipasquale A, Yanovsky A - Acta Crystallogr Sect E Struct Rep Online (2009)

Bottom Line: The title compound, C(12)H(19)BrN(4)O, represents the minor component of the two products obtained in a series of transformations involving the Grignard reaction of tert-butoxy-carbonyl-protected 4-amino-cyclo-hexa-none with MeMgBr, and subsequent inter-action of the obtained amino-substituted cyclo-hexa-nol with 4-chloro-6-methyl-pyrimidin-2-amine followed by bromination with N-bromo-succinimide.The X-ray structure showed that this product represents a trans isomer with respect to the amino and hydr-oxy substituents in the cyclo-hexyl ring; the dihedral angle between the amino-pyrimidine plane and the (noncrystallographic) mirror plane of the substituted cyclo-hexyl fragment is 33.6 (3)°.Only two of the four potentially 'active' H atoms participate in inter-molecular N-H⋯O and O-H⋯N hydrogen bonds, linking the mol-ecules into layers parallel to the (10) plane.

ABSTRACT
The title compound, C(12)H(19)BrN(4)O, represents the minor component of the two products obtained in a series of transformations involving the Grignard reaction of tert-butoxy-carbonyl-protected 4-amino-cyclo-hexa-none with MeMgBr, and subsequent inter-action of the obtained amino-substituted cyclo-hexa-nol with 4-chloro-6-methyl-pyrimidin-2-amine followed by bromination with N-bromo-succinimide. The X-ray structure showed that this product represents a trans isomer with respect to the amino and hydr-oxy substituents in the cyclo-hexyl ring; the dihedral angle between the amino-pyrimidine plane and the (noncrystallographic) mirror plane of the substituted cyclo-hexyl fragment is 33.6 (3)°. Only two of the four potentially 'active' H atoms participate in inter-molecular N-H⋯O and O-H⋯N hydrogen bonds, linking the mol-ecules into layers parallel to the (10) plane.
