Thiourea → HCID 66820895, compound

Participants

Reaction Steps

The 6-chloromethyl-2-pyridylacetonitrile (200 mg, 1.20 mmol) and thiourea (101 mg, 1.32 mmol) were mixed in 1 ml of methanol. The mixture was heated to reflux for 3 to 4 hours. The reaction mixture was evaporated. After that, 1 ml of methanol and 4 ml of acetone were added and the mixture was stirred for one hour. The crystalline material was filtered and the product was dried under high vacuum overnight to yield 216 mg (0.89 mmol, yield 74%) of product as off white crystals, with purity greater than 95%. 1H NMR (300 MHz, d6-DMSO) δ 4.29 (s, 2H), 4.64 (s, 2H), 7.41 (d, 1H, J=7.78), 7.51 (d, 1H, J=7.78), 7.91 (t, 1H, J=7.78), 9.46 (s, 4H). (M+H) 207.00
