Participants

Reaction Steps

2-(4-Aminophenylthio)-6-(azetidin-1-yl)-N-(3-methyl-1H-pyrazol-5-yl)pyrimidin-4-amine (200 mg, 0.57 mmol) was taken up in pyridine (2 mL) and p-toluoyl chloride (0.187 mL, 1.42 mmol) was added dropwise at room temperature. After 15 minutes the reaction mixture was concentrated in vacuo and the residue taken up in methanol (3 mL). Sodium methoxide (25% w/w solution in MeOH, 1 mL) was added and the resulting cloudy solution stirred at room temperature for 15 minutes. The reaction mixture was purified directly by chromatography (silica, 5-100% EtOAc-petrol gradient elution) to give the title compound (91 mg, 34%) as a white solid. 1H NMR: (400 MHz, DMSO) 1.99 (3H, brs), 2.33 (2H, qn), 2.40 (3H, s), 3.88 (4H, t), 5.38 (1H, brs), 5.59 (1H, vbrs), 7.36 (2H, d), 7.53 (2H, d), 7.87 (2H, d), 7.91 (2H, d), 9.20 (1H, brs), 10.36 (1H, s), 11.66 (1H, brs); MS (ES+) 472.
