실험 절차
A mixture of 1,3-dichloro-8,8-dimethyl-5,6-dihydro-8H-7-oxa-2,4,4b,9-tetraaza-fluorene (100 mg, 0.366 mmol), 2,2-dimethyl-morpholine (84 mg, 0.732 mmol) and triethylamine (77 μL, 0.55 mmol) in IMS (2 mL) was heated at 140° C. for 20 mins in a microwave reactor, then concentrated in vacuo. The resulting residue was purified by column chromatography (SiO2, 10% ethyl acetate in cyclohexane) affording 3-Chloro-1-(2,2-dimethyl-morpholin-4-yl)-8,8-dimethyl-5,6-dihydro-8H-7-oxa-2,4,4b,9-tetraaza-fluorene as a white solid (110 mg, 85%). LCMS (method A): RT=3.51 min, [M+H]+=352.
