Reaction Steps

Following the procedure for the preparation of (1S,2S)-1-{[5-(2,4-dichlorophenyl)-3,6-diethylpyrazin-2-yl]amino}-2,3-dihydro-1H-inden-2-yl 4-nitrobenzoate but substituting (1R,2S)-1-[(3,6-diethylpyrazin-2-yl)amino]-2,3-dihydro-1H-inden-2-ol and making non-critical variations provided the title compound as a yellow solid. IR (diffuse reflectance) 1725, 1568, 1550, 1527, 1498, 1467, 1392, 1372, 1349, 1320, 1273, 1119, 1103, 1014, 719 cm−1; OAMS supporting ions at: ESI+ 577.1; MS (CI) m/z 577 (MH+); HRMS (FAB) calcd for C30H26CL2N4O4+H1 577.1409, found 577.1393; [α]25D=−118 (c 0.62, methylene chloride).
