実験手順

A solution containing 1 eq each of tert-butyl (3R,4R)-1-(3-aminopyridin-4-yl)-4-(tert-butyldimethylsilyloxy)piperidin-3-ylcarbamate, 2-bromothiazole-4-carboxylic acid, HOAT and EDC in DMF, at a concentration of 0.5 M, was stirred for 60 hours. The solution was diluted with EtOAc and was washed with H2O (4×), NaCl(sat.), was dried over MgSO4, was filtered and the volatiles were removed in vacuo yielding tert-butyl (3R,4R)-1-(3-(2-bromothiazole-4-carboxamido)pyridin-4-yl)-4-(tert-butyldimethylsilyloxy)piperidin-3-ylcarbamate, LCMS (m/z): 612.2/614.2 (MH+); LC Rt=4.26 min.
