Reaction Steps

A suspension of 4-methanesulfonylamino-butyramide (0.50 g, 2.8 mmol) and Lawesson's reagent (0.56 g, 1.4 mmol) in THF (50 mL) was stirred at room temperature for 45 minutes. During this time all of the solid dissolved. The solution was concentrated and purified by flash chromatography (79:1 EtOAc:MeOH) to afford the title compound of Step C (0.41 g); 1H NMR (400 MHz, CDCl3) δ 3.29 (s, 3H), 3.07-3.11 (m, 2H), 2.91 (s, 3H), 2.62-2.66 (m, 2H), 1.93-1.99 (m, 2H); MS 197 (M++1).
