Participants

Reaction Steps

To a suspension of benzyl 2-aminoethylcarbamate LIX (3 g; 15.45 mmol) in anhydrous ethanol (20 mL) was added carbon disulfide (0.47 mL; 7.73 mmol). The mixture was heated under gently reflux for 22 h. After cooling to r.t., the product precipitated and was filtered, washed with anhydrous ethanol (3×) and air dried. Benzyl N-(2-{[(2-{[(benzyloxy)carbonyl]amino}ethyl)carbamothioyl]amino}ethyl)carbamate LX was obtained as white solid (2.97 g; 6.90 mmol; 89.3% yield). 1H NMR (DMSO-d6) 3.10-3.14 (m, 4H), 3.37-3.42 (m, 4H), 5.00 (s, 4H), 7.30-7.37 (m, 12H), 7.54 (brs, 2H); ESIMS found for C21H26N4O4S m/z 431.4 (M+H).
