Trityl chloride → N-(2-methyl-1-(tritylamino)propan-2-ylcarbamothioyl)benzamide

Participants

Reaction Steps

2-Methyl-N-1-tritylpropane-1,2-diamine, prepared from 2-methylpropane-1,2-diamine and trityl chloride (EP1204654) in yield of 44%, was coupled with benzoylisothiocyanate to give N-(2-methyl-1-(tritylamino)propan-2-ylcarbamothioyl)benzamide (US2008/45579) which was then reacted with lithium hydroxide to give 1-(2-methyl-1-(tritylamino)propan-2-yl)thiourea. Yield 79%. 1H NMR (400 MHz, CDCl3) δ 7.40-7.12 (m, 16H), 6.30 (s, 1H), 2.38 (d, J=8.3, 2H), 2.15 (t, J=8.3, 1H), 1.31 (s, 6H)
