Procedure

5-(Piperidin-4-ylmethoxy)quinazoline-2,4-diamine (50 mg; 0.18 mmol) was shaken for 60 hours at room temperature in the presence of 3-(morpholino)propyl polystyrene sulfonamide (PS-NMM) (160 mg; 0.4 mmol) and 3,4-difluorobenzoyl chloride (65.3 mg; 0.37 mmol) in 4 mL N,N-dimethylformamide. Tris-(2-aminoethyl)aminomethyl polystyrene (PS-Trisamine) (112 mg; 0.4 mmol) was then added to the mixture and continued to shake for an additional 2 hours. Resins were filtered off and rinsed with methanol. Filtrate was concentrated at reduced pressure, and residue was triturated with 2 mL 1 N NaOH and ethanol (1:1). Solids were collected by filtration to yield [4-(2,4-diamino-quinazolin-5-yloxymethyl)-piperidin-1-yl]-(3,4-difluorophenyl)-methanone (117.4 mg; 76% yield). 1HNMR (400 MHz, DMSO-d6) δ 7.51 (m, 2H), 7.35 (t, J=8.4 Hz, 1H), 7.26 (m, 3H), 6.77 (d, J=8.4 Hz, 1H), 6.54 (d, J=8.4 Hz, 1H), 5.94 (br s, 2H), 4.50 (br s, 1H), 4.03 (d, J=6.0 Hz, 2H), 3.60 (br s, 1H), 3.11 (br s, 1H), 2.82 (br s, 1H), 2.22 (s, 1H), 1.87 (br s, 1H), 1.75 (br s, 1H), 1.31 (m, 2H).
