Reaction Steps

A solution-of N-(2-bromo-4-(1-methylethyl)phenyl)-N-ethyl-4-((4,4-ethylenedioxypiperidino)carbonyl)-6-methylpyrimidinamine (260 mg) in a mixture of a 1N HCl solution (2.5 mL) and THF (2.5 mL) was stirred at reflux temperature for 20 h. The reaction mixture was poured into a 1N NaOH solution, and extracted three times with ethyl acetate. The combined organic layers were dried over MgSO4, filtered and concentrated in vacuo to give the title product as a yellow oil (240 mg, 100% yield, Rf 0.75): NMR (CDCl3, 300 MHz): 7.5 (s, 1H), 7.2 (d, 1H, J=8), 7.1 (d, 1H, J=8), 6.8 (br s, 1H), 4.3-4.1 (m, 1H), 3.95-3.85 (m, 1H), 3.75-3.6 (m, 1H), 3.55-3.4 (m, 1H), 2.95-2.85 (m, 1H), 2.6-2.3 (m, 4H), 2.0-1.6 (m, 2H), 1.4-1.15 (m, 12H); CI-HRMS: Calcd (C22H27BrN4O2): 459.1396 (M+H); Found: 459.1386.
