Reaction Steps

2-chloro-8-(tetrahydro-2H-pyran-4-yloxy)quinazoline (1 g, 3.8 mmol), trans-4-amino-cyclohexanol (0.524 g, 4.56 mmol) and DBU (0.69 g, 4.56 mmol) were suspended in MeCN (10 mL). The mixture was heated at reflux for 10 h. TLC showed the reaction was complete. The mixture was concentrated in vacuo, the residue was purified by HPLC to yield the title compound (0.373 g, 28%) as a yellow solid. 1H NMR (400 MHz, CDCl3): δ 10.817 (d, 1H), 9.120 (s, 1H), 7.351 (m, 2H), 7.210 (m, 1H), 4.630 (m, 1H), 4.118 (m, 1H), 4.041 (m, 2H), 3.712 (m, 1H), 3.524 (m, 2H), 2.001 (m, 8H), 1.620 (q, 2H), 1.419 (q, 2H)
