N-Aminomorpholine → HCID 25099733, compound

Participants

Reaction Steps

2-Benzoyl-pyrimidine-5-carboxylic acid (50 mg, 0.22 mmol) is dissolved in anhydrous DCM (5 mL), and a 2 M oxalyl chloride (0.26 mmol, 0.13 mL) solution in DCM is added at rt followed by one drop of DMF. The mixture is stirred at rt for 2 h, and then concentrated in vacuo. The residue is dissolved in DCM (5 mL), and morpholine-4-ylamine (0.24 mmol, 25 mg) is added, followed by DIPEA (0.44 mmol, 57 mg). The reaction mixture is stirred at rt overnight, and then concentrated in vacuo. The residue is purified by silica gel column chromatography eluting with 10% MeOH in DCM to afford 2-benzoyl-pyrimidine-5-carboxylic acid morpholin-4-ylamide (42 mg) as a solid. MS: 313 (M+H). IC50=342 nM.
