Procedure
The title compound was prepared from the product of Example 1, step J, and trans-3-(2,3-dihydrobenzofuran-5-yl)prop-2-enoic acid, by the method of Example 1, step K, giving a solid that was mostly the more polar cyclohexyl diastereomer by LCMS. Mass spectrum (LCMS, ESI pos.) calcd. for C32H38N4O3: 527 (M+H). Found: 527
