Reaction Steps

1-Chloropropan-2-one (0.334 mL, 4.20 mmol) and methyl 2-amino-2-thioxoacetate (500 mg, 4.20 mmol) was dissolved in EtOH. The reaction solution was heated to 80° C. for overnight, cooled to RT, concentrated and purified with a silica gel column by ISCO CombiFlash® chromatography eluting with 10%-35% EtOAc/Haptane to give the title compound as a yellowish oil (243 mg, 33.8%) as the ethyl ester. A methyl ester product was isolated as a yellow solid (104 mg, 15.8%).
