実験手順

(5R,7R)-4-Chloro-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-yl 4-nitrobenzoate (65 mg, 0.195 mmol) was dissolved in i-PrOH (5 mL), and then tert-butyl 1,4-diazepane-1-carboxylate (51 mg, 0.253 mmol) was added. N,N-Diisopropylethylamine (49 mg, 0.350 mmol) was added, and the reaction mixture was heated to 80° C. for 12 hours, after which the solvents were removed under reduced pressure. The resulting residue was taken up into EtOAc and then washed twice with water and once with brine. The organic portion was dried over magnesium sulfate, filtered, and then concentrated. The resulting residue was purified via silica gel chromatography to give tert-butyl 4-((5R,7R)-5-methyl-7-(4-nitrobenzoyloxy)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)azepane-1-carboxylate (78 mg, 81%). LCMS (APCI+) M+=498.1, Rt=3.81 min.
