To a solution of tetrahydofurfurylamine (2 mL) in EtOH (20 mL) were added 5 N NaOH (3.9 mL) and carbon disulfide (1.17 mL), and the mixture was stirred for 1.5 h. Methyl 4-chlorobutyrate (2.4 mL) was then added, and the mixture was stirred overnight. Upon quenching with saturated NaCl solution the mixture was extracted with ether. Chromatography on silica gel gave the desired 4-(tetrahydrofuran-2-ylmethylthiocarbamoylsulfanyl)-butyric acid methyl ester product (1.1 g).
