Reaction Steps

A solution of tert-butyl (3S,5R)-5-methylpiperidin-3-ylcarbamate (1.5 equiv.) and 6-(6-(thiazol-2-yl)pyridin-2-yl)quinolin-4-yl trifluoromethanesulfonate (1.0 equiv.) and DIEA (2.0 equiv.) in i-PrOH was heated in a microwave at 150° C. (5×20 min). Upon cooling the material was purified directly 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 (3S,5R)-5-methyl-1-(6-(6-(thiazol-2-yl)pyridin-2-yl)quinolin-4-yl)piperidin-3-amine (51%). LC/MS=402.0 (M+H), LC=2.16 min.
