2H-Azepin-2-one, 3-aminohexahydro- → 3-(2,5-Dichloropyrimidin-4-ylamino)azepan-2-one

Participants

Reaction Steps

A mixture of (±)-α-amino-ε-caprolactam (256 mg, 2.0 mmol), 2,4,5-trichloropyrimidine (366 mg, 2.0 mmol, 1 equiv.) and NaHCO3 (168 mg, 2 mmol, 1 equiv.) in a mixture of MeOH (12 mL) and H2O (6 mL) was stirred at room temperature for 15 h. The resulting precipitate was collected by vacuum filtration and washed with small amounts of MeOH and water, providing the product 3-(2,5-dichloropyrimidin-4-ylamino)azepan-2-one; ESMS m/z 275.0 (M+H+).
