Methanesulfonyl chloride → 5-Acetyl-1-(1,3-benzodioxol-5-yl)-8-[(methylsulfonyl)amino]-4,5-dihydro-1h-pyrazolo[4,3-c]quinoline-3-carboxamide

Reaction Steps

The title material from Example 17 step 6 (300 mg, 0.000767 mol) was dissolved in pyridine (5 mL), and to this solution was added methane sulfonyl chloride (88 mg, 0.000767 mol). The resulting solution was stirred at room temperature for 18 hours. The reaction was then concentrated in vacuo, and the resulting solids were triturated with water and the product was isolated by vacuum filtration. 88 mg. (MW=469.48, 25% yield). LC/MS m/z=470.3 (m+1).
