Reaction Steps

A mixture of compound 7b (8 g, 24.6 mmoles) and potassium carbonate (17 g, 123 mmoles) in acetone (250 mL) was refluxed for 1 hour, then (2R,6S)-4-(2-chloroethyl)-2,6-di methyl morpholine (25.9 mmoles) was added dropwise. The mixture was refluxed overnight then was cooled and filtered. The resulting solid was dried and purified via preparative HPLC (channel A=CH3CN+0.1% formic acid; channel B=H2O+0.1% formic acid: flow=40 ml/min; gradient=10%-45% of eluent A in 15 minutes) providing N-[(1-{2-[(2R,6S)-2,6-dimethylmorpholin-4-yl]ethyl}piperidin-4-yl)methyl]-5-methoxy-1H-indazole-3-carboxamide 25 (48.3% yield)
