Ammonia → Urea, 1-pentyl-2-thio-

Participants

Reaction Steps

Pentylisothiocyanate (10 g, 0.08 mol) was added slowly (about 10 mins) to a mixture of ammonia (50 mL, 0.2 mol) in methanol (7 N) at 0° C. After being stirred at room temperature for 1 h, the solvent was stripped off and the product was obtained as a white solid (10 g, 88.4%), which was used for next step without further purification. LCMS calculated for C6H15N2S: (M+H) 147.1; found 147.1.
