Propylamine → 6-Methyl-2-(propylamino)pyrimidine-4-carboxylic acid

Participants

Reaction Steps

A solution of 2-chloro-6-methylpyrimidine-4-carboxylic acid (100 mg, 0.58 mmol) and propylamine (0.48 mL) in dioxane (1 mL) is stirred at 70° C. for 18 h. The reaction mixture is concentrated and purified by prep. HPLC (X-Bridge) to give 6-methyl-2-propylamino-pyrimidine-4-carboxylic acid (81 mg) as a yellow crystalline solid; LC-MS: tR=0.56 min, [M+H]+=196.08; 1H NMR (D6-DMSO): δ 0.89 (t, J=7.3 Hz, 3H), 1.53 (m, 2H), 2.32 (s, 3H), 3.25 (m, 2H), 6.92 (s, 1H), 7.36 (s br, 1H), 13.2 (s br, 1H).
