Reaction Steps

α-cyano-N-isopropyl-N-(2-mercaptobenzothiazol-6-yl)acetamide (71 mg, 0.244 mmol) and N-ethyl-4-formylbenzenesulfonamide (52 mg, 0.244 mmol) were combined in absolute ethanol (1 ml). The mixture was stirred 15 minutes with activated 4A molecular sieves in a sealed vessel. Piperidine (27 μL, 0.268 mmol) was added and the mixture was heated to 80° C. After 1.5 hours, the solution was concentrated in vacuo and purified by preparative TLC (50% ethyl acetate, 50% hexanes) to yield 19 mg (16%). 1H NMR(CDCl3) δ=1.08 (t, 3H), 1.20 (m, 6H), 2.99 (t, 2H), 4.98 (m, 1H), 5.41 (m, 1H), 7.17 (d, 1H), 7.32 (m, 3H), 7.81 (d, 2H), 7.88 (d, 2H), 7.96 (s, 1H).
