Methanesulfonyl chloride → Methanesulfonic acid 1-(6-{(1R,4S)-4-[3-(5-tert-butyl-2-methyl-2H-pyrazol-3-yl)-ureido]-1,2,3,4-tetrahydro-naphthalen-1-yloxy}-[1,2,4]triazolo[4,3-a]pyridin-3-yl)-piperidin-4-ylmethyl ester

Participants

Reaction Steps

Methanesulfonyl chloride (8.8 μL, 0.13 mmol) was added to a solution of Intermediate 14g (50 mg, 0.08 mmol) and DIPEA (46 μL, 0.26 mmol) in DCM (1.5 mL) and the reaction mixture was stirred at RT for 1 h. The mixture was diluted with DCM (5 mL) and washed with water (3×5 mL). The organic layer was passed through a phase separator and concentrated in vacuo to afford the title compound (57 mg, 100%). LCMS (Method 3): Rt: 3.21 min, m/z 651 [MH+].
