tert-Butylcyclohexane → HCID 178445796, compound

Participants

Reaction Steps

Coupling of t-butyl cyclohexane to the core was performed similar to that described for (R)-4-(6-(trans-4-tert-butylcyclohexyloxy)-5-iodoquinazolin-2-yl)-4-methyloxazolidin-2-one (Example 60) utilizing (R)-4-(6-hydroxyquinazolin-2-yl)-4-methyloxazolidin-2-one as the starting material. Deprotection was then performed similar to that described for (R)-2-amino-2-(6-(trans-4-tert-butylcyclohexyloxy)-5-(trifluoromethyl)quinazolin-2-yl)propan-1-ol (Example 61) to give the title compound. 1H NMR (MeOD) δ: 9.37 (s, 1H), 7.92 (d, J=9.3 Hz, 1H), 7.57 (dd, J=9.2, 2.6 Hz, 1H), 7.42 (d, J=2.5 Hz, 1H), 4.34-4.49 (m, 1H), 4.05 (d, J=10.8 Hz, 1H), 3.79 (d, J=10.8 Hz, 1H), 2.29 (d, J=10.8 Hz, 2H), 1.93 (d, J=12.8 Hz, 2H), 1.54 (s, 3H), 1.38-1.51 (m, 2H), 1.21-1.35 (m, 2H), 1.08-1.19 (m, 1H), 0.93 (s, 9H). MS (M+1): 358.20.
