To a stirred solution of 6-[({[(1-methyl-1H-tetrazol-5-yl)(phenyl)methylene]amino}oxy)methyl]pyridin-2-amine (150.0 mg, 0.485 mmol) in dichloromethane (5 mL), under argon atmosphere, were added pyridine (0.078 mL, 0.97 mmol) and S-butyl carbonochloridothioate (133 mg, 0.87 mmol) at room temperature. After stirring at room temperature overnight, the reaction mixture was diluted with dichloromethane (50 mL), filtered through “Chem Elut” cartridge, washed with dichloromethane (50 mL) and the filtrate was concentrated in vacuo yielding to S-butyl {6-[({[(1-methyl-1H-tetrazol-5-yl)(phenyl)methylene]amino}oxy)methyl]pyridin-2-yl}carbamothioate as a honey [82 mg, yield 38%; HPLC/MS m/z=426 (M+H); logP(HCOOH)=4.25].
