Sodium hydride → (1S,4R)-4-[3-(4-Methyl-4-triisopropylsilanyloxy-piperidin-1-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yloxy]-1,2,3,4-tetrahydro-naphthalen-1-ylamine

Reaction Steps

To a solution of Intermediate A (111 mg, 0.680 mmol) in DMF (2 mL) was added NaH (60% in oil, 68 mg, 1.70 mmol) and the mixture stirred at RT for 20 min, before Intermediate 79d (230 mg, 0.566 mmol) was added. This mixture was stirred at 60° C. for 1 h. The cooled reaction mixture was diluted with EtOAc (100 mL), washed with water (2×), brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by FCC, using 0-10% [2M NH3 in MeOH] in DCM, to give the title compound (160 mg, 51%). LCMS (Method 1): Rt 3.06 min, m/z 550 [MH+].
