Reaction Steps

A mixture of 4-pivalamidopyridin-3-yl diisopropylcarbamodithioate (5.0 g, 14 mmol) and NaOH (1.1 g, 28 mmol) in MeOH (100 mL) was stirred at 20° C. for 20 hours. The reaction was concentrated under reduced pressure and the residue was purified by silica gel column chromatography, eluting with EtOAc/petroleum ether (1:8) to give the desired product as a white solid (3.8 g, 93% yield). 1H NMR (500 MHz, CDCl3): δ 8.24 (t, J=2.0 Hz, 1H), 6.69 (d, J=5.5 Hz, 1H), 4.90 (s, 2H), 1.64-1.30 (m, 14H). LCMS (ESI) m/z: 270.1 [M+H+].
