Reaction Steps

To a solution of 4-[4-Amino-quinazolin-7-ylmethyl]-5-methyl-3-oxo-2-propyl-piperazine (12 mg, 0.04 mmol, EXAMPLE 888) in 2 mL of DMF is added 4-chlorophenyl isocyanate (9 mg, 0.06 mmol). After stirring at 100° C. for 1 h, the solution is concentrated. The crude product is purified by RP-HPLC eluting in a gradient of 10% CH3CN/H2O (0.1% TFA) to 70% CH3CN/H2O (0.1% TFA) and the appropriate product fractions are combined and lyophilized to provide the title compound (16 mg, 0.03 mmol) as a white solid. 1H NMR (d6-DMSO, 300 MHz) δ9.74 (bs, 2H), 8.77 (m, 2H), 8.35 (m, 1H), 7.56 (m, 2H), 7.46 (d, 2H), 7.21 (d, 2H), 5.00-4.38 (m, 3H, rotamers), 4.20 (m, 1H, rotamers), 3.58 (m, 1H, rotamers), 3.10 (m, 1H), 1.86 (m, 2H), 1.33 (m, 2H), 1.08 (m, 3H, rotamers), 0.90 (t, 3H). ISP MS, [M+H]+=467, 469 (Cl pattern).
