1,1-Carbonyldiimidazole (0.97 g, 6 mmol) was added to a solution of 2-[4-Amino-5-(5-chloro-2-isopropyl-4-methoxy-phenoxy)-pyrimidin-2-ylamino]-(R)-propan-1-ol from Example 4 (0.22 g, 0.6 mmol) in 20 mL of THF at room temperature. The mixture was stirred for 2 hours and methylamine (3 mL, 2M/THF, 0.6 mmol) was added. The reaction mixture was stirred overnight and concentrated under reduced pressure, diluted with water (75 mL), and extracted with EtOAc (2×75 mL). The organic phase was washed with Brine and dried with MgSO4. The solution was filtered and concentrated. The residue was purified on two Silica preparative TLC plates (20×40 cm) eluting with 5% MeOH/dichloromethane affording 143 mg of methyl-carbamic acid 2-[4-amino-5-(5-chloro-2-isopropyl-4-methoxy-phenoxy)-pyrimidin-2-ylamino]-propyl ester: MS (M+H); 424: MP; 63.5-69.4° C.
