2,4-Dimethoxybenzeneboronic acid → (1R,2S)-1-{[5-(2,4-dimethoxyphenyl)-3,6-diethylpyrazin-2-yl]amino}-2,3-dihydro-1H-inden-2-ol

Participants

Reaction Steps

Following the procedure for the preparation of (1R,2S)-1-{[5-(2,4-dichlorophenyl)-3,6-diethylpyrazin-2-yl]amino}-2,3-dihydro-1H-inden-2-ol but substituting 2,4-dimethoxyphenylboronic acid and making non-critical variations provided the title compound as an off-white foam. IR (diffuse reflectance) 2966, 2934, 1610, 1567, 1483, 1391, 1303, 1280, 1253, 1208, 1159, 1128, 1046, 1034, 741 cm−1; OAMS supporting ions at: ESI+ 420.1; MS (EI) m/z 419 (M+); HRMS (FAB) calcd for C25H29N3O3+H1 420.2287, found 420.2278.
