Methanol → 5-Amino-2-(2-(methylsulfonyl)ethyl)isoquinolin-1(2H)-one

Participants

Reaction Steps

Into a 250 ml round bottom flask was combined 2-(2-(methylsulfonyl)ethyl)-5-nitroisoquinolin-1(2H)-one (1.20 g, 0.00405 mol) Palladium/C (0.04 g, 0.0004 mol) and methanol (40 mL, 1 mol). The flask was evacuated and purged with hydrogen 3 times. The mixture was stirred at room temperature under hydrogen (1 atm) for three hours. The mixture was filtered over celite and the filtrate was reduced in vacuo. The mixture was purified by column chromatography using a Methanol:methylene chloride (0-10%) gradient. The combined pure fractions were reduced in vacuo to yield the title compound as an off white solid.
