Reaction Steps

Note: For the preparation of the starting material compound 1, see Example 147. Into a 50-mL round-bottom flask, was placed 1-N-[7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]cyclohexane-1,4-diamine (170 mg, 0.59 mmol, 1.00 equiv), 2-chloro-1-(pyrrolidin-1-yl)ethan-1-one (89 mg, 0.60 mmol, 1.00 equiv), KI (10 mg, 1.00 equiv) and ethanol (20 mL) at room temperature under nitrogen. The resulting solution was stirred overnight at 90° C. in an oil bath. The solvent was removed under reduced pressure. The crude product (180 mg) was purified by Prep-HPLC with the following conditions (SHIMADZU): Column, SunFire Prep C18, 19*150 mm 5 um; mobile phase, water with 0.05% NH4HCO3 and CH3CN (6.0% CH3CN up to 50.0% in 21 min); Flow rate, 20 mL/min; UV detection at 254/220 nm. The product-containing fractions were collected and partially evaporated to remove water and CH3CN under reduced pressure. The residue was lyophilized overnight to give the desired trans-1-(pyrrolidin-1-yl)-2-[[4-([7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]amino)cyclohexyl]amino]ethan-1-one (20.5 mg) as a white solid and trans-2-[[2-oxo-2-(pyrrolidin-1-yl)ethyl][4-([7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]amino)cyclohexyl]amino]-1-(pyrrolidin-1-yl)ethan-1-one (26.7 mg) as a white solid, respectively.
