Participants

Reaction Steps

To a ice cold solution of 2-methylpropan-1-ol (110 mg, 1.483 mmol) in DMF (1483 μl) was added sodium hydride (59.3 mg, 1.483 mmol) under nitrogen and stirred for 10 min to this was then added a solution of 1-(6-fluoro-2-methoxypyridin-3-yl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (122 mg, 0.297 mmol) in DMF (1483 μl) and stirred for 16 h slowly raising the temperature to ambient temperature. The reaction mixture was quenched with MeOH, concentrated and purified via reverse phase HPLC (0.1% NH4OH in ACN and water as mobile phase) to obtain 1-(6-isobutoxy-2-methoxypyridin-3-yl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide as light yellow solid (56 mg, 120 mmol, 41% yield). m/z (ESI) 466.2 (M+H)+.
