    • 4 (1.00 g, 8.3 mmol). The reaction was heated to reflux for 1.5 h, cooled to room temperature, diluted with dichloromethane (300 mL), filtered, and concentrated in vacuo. Purification by flash chromatography (6 × 15 cm silica gel, 40 → 80% acetone/dichloromethane) provided 12 (276 mg, 19%) and trans-2 (455 mg, 31%), both as pale yellow foams.

    • The FTase inhibitory activity and dog pharmacokinetic (PK) properties of 1 and the corresponding 2-methylimidazole analogue of 1 are very similar, suggesting that the methyl groups in trans-13 and cis-13 contribute little to their inhibitory and PK activities (Merck Research Laboratories, unpublished results)

    • (a) Molecular modeling results, with relative energies in kcal/mol shown in parentheses: trans-13 diequatorial half-chair (0.00); trans-13 diaxial half-chair (1.56); cis-13 equatorial-)ArCN) - axial-(piperazinone) half-chair (0.18); cis-13 axial-(ArCN) - equatorial-(piperazinone) half-chair (0.59); cis-13 diaxial boat (5.46). Conformations were generated using the metric matrix distance geometry algorithm JG (S. Kearsley, Merck Research Laboratories, unpublished). The structures were subjected to energy-minimization within Macromodel (ref 15b) using the MMFF force field.
