実験手順

2-(4-Chloro-5-trifluoromethyl-pyrimidin-2-ylamino)-3-methoxy-5-methyl-8,9-dihydro-5H-7-oxa-5-aza-benzocyclohepten-6-one and 2-Amino-N-methyl-benzamide (85 mg, 0.56 mmol;) was stirred in isopropyl alcohol (5.00 mL, 65.3 mmol;) with 10-camphorsulfonic acid (150 mg, 0.63 mmol;) at 120° C. in microwave for 30 min×3. The reaction mixture was concentrated and then extracted with DCM (20 mL) and washed with sat. NaHCO3 (20 mL) followed by water. The organic layer was dried over MgSO4, filtered and concentrated. The residue was chromatographed on ISCO flash system (0-100% Hex:EtOAc) to obtain the product as one of multiple peaks by UV. The fractions were concentrated and triturated in Et2O to obtain a filterable solid (25 mg, 29%). mp: 210-212° C.
