4-Piperidinol, 1-methyl- → HCID 10228736, compound

Participants

Reaction Steps

1-Methyl-piperidin-4-ol (56 mg, 0.5 mmol) was dissolved in 2 mL of DMSO. To the solution was added potassium tert-butoxide (56 mg, 0.5 mmol). The solution was stirred at room temperature for 1 h. The solution was then added to a solution of 3-{6-[(2,2-Dimethyl-propyl)-methyl-amino]-2-methanesulfonyl-5-nitro-pyrimidin-4-ylamino}-4,N-dimethyl-benzamide (4 mg, 0.01 mmol) in 0.5 mL of DMSO. The solution was stirred at 80° C. for 3 h, and extracted with ethyl acetate and water. The organic layer was washed with water, brine, dried over MgSO4, and evaporated under vacuum. The residue was purified by semi-preparative hplc column to afford 0.7 mg of the product (Yield: 16%). MS (m/z) calcd for C25H37N7O4 (MH+), 500.2, found, 500.1.
