Procedure
Following the procedure for the preparation of 5-(2,4-dichlorophenyl)-N-[(1R,2S)-2-ethoxy-2,3-dihydro-1H-inden-1-yl]-3,6-diethylpyrazin-2-amine but substituting (1R,2S)-1-{[5-(2,4-dichlorophenyl)-3,6-dimethylpyrazin-2-yl]amino}-2,3-dihydro-1H-inden-2-ol and methyl iodide, and making non-critical variations provided the title compound as a oil: 1H NMR (300 MHz, CDCl3) δ) 7.51, 7.43, 7.37–7.25, 5.86, 5.40, 4.28, 3.43, 3.23, 3.06, 2.42, 2.25; HRMS (FAB) calcd for C22H21Cl2N3O+H 414.1140, found 414.1143.
