A solution of 4-[6-(6-chloro-2-methyl-pyridin-3-ylamino)-5-methyl-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester (613 mg, 1.46 mmol) in 15 mL morpholine was reacted under microwave irradiation at 180° C. for 14 hours. Mixture was concentrated and purified by HPLC to give Compound A91 as a white solid (427 mg, 58%). 1H NMR (MeOH-d4, 400 MHz) δ 1.03-1.05 (d, 6H), 1.51-1.60 (m, 2H), 1.78-1.85 (m, 2H), 1.98 (s, 3H), 2.29 (s, 3H),3.19-3.25 (m, 2H), 3.54-3.58 (m, 6H), 3.65-3.67 (m, 4H), 4.65-4.70 (m, 1H), 5.20-5.25 (m, 1H), 7.08-7.10 (d, 1H), 7.68-7.71 (d, 1H), 8.07 (s, 1H). Exact mass calculated for C24H34N6O4 470.26, found 471.3 (MH+).
