Benzoyl isothiocyanate → 1-Benzoyl-3-(3-(benzyloxy)pyridin-2-yl)thiourea

Participants

Reaction Steps

A 1 L round-bottomed flask was charged with benzoyl isothiocyanate (22.4 g, 137 mmol), 3-(benzyloxy)pyridin-2-amine (25 g, 125 mmol), and THF (200 mL). The reaction mixture was stirred at room temperature for 2 hours and the diluted with hexanes to 1 L, and then filtered to afford 1-benzoyl-3-(3-(benzyloxy)pyridin-2-yl)thiourea (44.4 g, 97.9% yield) as a yellow solid. 1H NMR (CDCl3) δ 9.00 (m, 1H), 8.08 (m, 1H), 7.87 (m, 1H), 7.62 (m, 1H), 7.54 (m, 2H), 7.41 (m, 5H), 7.27 (m, 1H), 7.02 (m, 1H), 5.22 (s, 2H). LCMS (25 to 95) Rt=2.64 min, (apci) m/z=201, 364 (M+H).
