Sodium hydride → 2-Amino-4-(cyclopropylmethyloxy)-6-(4-fluorophenyl)pyrido[3,2-d]pyrimidine

Participants

Reaction Steps

To a solution of 2-acetamido-4-(1,2,4-triazolyl)-6-(4-fluorophenyl)-pyrido[3,2-d]pyrimidine (52 mg, 0.15 mmol) in cyclopropylmethanol (1 ml) and dioxane (3 ml) was added NaH (60% dispersion in mineral oil, 0.25 mmol, 15 mg). The reaction mixture was stirred overnight at room temperature. The solvents were evaporated in vacuo, and the residue was purified by preparative TLC, the mobile phase being a methanol/dichloromethane mixture in a ratio of 10:90, yielding the pure title compound (22 mg, yield: 47%) which was characterised as follows: MS (m/z): 311 ([M+H]+, 100).
