4-(lsoquinolin-6-yloxy)-cyc.ohexanone (27); A suspension of 9 g triphenylphosphine (bound to polystyrene, Argonaut, 1.6 mmol/g, 14.4 mmol) and 1.57 ml_ (1.74 g, 10 mmol) diethyl azocarboxylate in 100 mL dichloromethane was stirred for 10 min under argon atmosphere. Then 1.45 g (10 mmol) <strong>[7651-82-3]6-hydroxy-isoquinoline</strong> and 1.58 g (10 mmol) 1 ,4-dioxa-spiro[4.5]decan-8-ol were added. After 40 min 1.39 mL (1 g, 10 mmol) triethyl amine was added and the reaction was allowed to shake for 16 h at room temperature. After filtration the organic layer was extracted with 1 N NaOH, dried over Na2SO4, filtered and concentrated in vacuo.The crude material (2.2 g) was dissolved in 200 mL acetone and 10 mL water. 1.5 g (7.9 mmol) of para-toluene sulfonic acid were added and the reaction was heated to reflux temperature for 6 h. Then the solvents were distilled off. The remainder was dissolved in dichloromethane and was extracted with aqueous Na2CO3 solution. After drying over Na2SO4, filtration and removal of the solvents the crude product was purified by flash chromatography to yield 1.19 g of 27 as a white solid. 1H-NMR (de-DMSO): delta = 9.16 (1 H, s), 8.41 (1 H, d, J = 5.8 Hz), 8.05 (1 H, d, J = 8.9 Hz), 7.70 (1 H, d, J = 5.8 Hz), 7.51 (1 H, d, J = 2.5 Hz), 7.36 (1 H, dd, J = 8.9 und 2.5 Hz), 5.04 (1 H, m), 2.44 (4H, m), 2.22 (2H, m), 2.11 (2H, m). MS: m/z = 242 (MH+). |

With di-isopropyl azodicarboxylate; triphenylphosphine; In tetrahydrofuran; at 20℃; | 2-Chloropyrimidin-5-ol (Intermediate No.86 Step 2, 200 mg,. 1.5 mmol) was dissolved in THF (5 mL) and triphenylphosphine (600 mg, 23 mmol) and 1,4-dioxa- spiro[4.5]decan-8-ol (365 mg, 2.30 mmol) was added, followed by DIAD (0.45 mL, 2.3 mmol). The reaction mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with EtOAc, washed with saturated NaHC03> and the aqueous phase was extracted with. EtOAc. The combined organic extracts were dried over Na2S04, filtered, dry loaded onto silica gel and the cpade residue was purified by flash chromatography (MPLC, 2-20percentDCM-hexane followed-by 5-60percent EtOAc-hexane) to give a crude residue which was further purified by reverse phase preparative HPLC (0-80percent MeCN-H20, 0.05percent TFA). Fractions containing the pure compound were collected and the free base was liberated by an EtOAc extraction and sat.NaHC03 wash to give 2-c oro-5-(l ,4-dioxaspiro[4.5]dec-8-yloxy)pyrimidine as a solid.LRMS (ESI) calc'd for C12H16C1N203 [M+H] +: 271 , Found: 271 |
