実験手順
A solution of (S)-tert-butyl 1-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinolin-4-yl)piperidin-3-ylcarbamate (1.0 equiv.), 6-(thiazol-2-yl)pyridin-2-yl trifluoromethanesulfonate (1.5 equiv.) and Pd(dppf)Cl2—CH2Cl2 (0.15 equiv.) in 3:1 DME/2M Na2CO3 was heated in a microwave at 100° C. for 20 minutes. Upon cooling, the solution was partitioned between EtOAc and Na2CO3(sat.) washed further with NaCl(sat.), dried over MgSO4, concentrated and purified by RP HPLC. Upon lyophilization, the Boc group was deprotected by treatment with 25% TFA/CH2Cl2, concentrated, purified by RP-HPLC and lyophilized to yield (S)-1-(6-(6-(thiazol-2-yl)pyridin-2-yl)quinolin-4-yl)piperidin-3-amine (40%). LC/MS=388.1 (M+H), LC=2.02 min.
