Reaction Steps

4-(4-Benzyl-1,3-thiazol-2-yl)-2-bromo-1-trifluoroacetylaminobenzene and (R)-1-(N-benzyloxycarbonylpyrrolidin-2-yl)-3-hydroxypropene were used. Chromatography using elution with a 1-5% either gradient in methylene chloride afforded the title compound (97%) as a white foam: FAB LRMS (m/z, relative intensity) 686 (MH2+, 100), 685 (MH+, 60), 684 (M+, 90), 640 (23), 578 (15), 441 (17), 371 (20); FAB HRMS calculated for [C33H29BrF3N3O3S.H]+ [with 79Br and 32S] 664.1145, found 664.1157.
