Synthetic Route of 932-01-4 , The common heterocyclic compound, 932-01-4, name is 4,4-Dimethylcyclohexanol, molecular formula is C8H16O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

10399] Step 1: To a DCM (45 mE) solution of the 4,4- dimethylcyclohexanol (200 mg, 1.56 mmol) was added tnethylamine(4.9 mE, 35 mmol). The solution was cooled to 0 C. before methanesulfonyl chloride (0.324 mE, 2.34 mmol) was added dropwise. The resulting mixture was allowed to warm to RT over 13 h. The reaction was diluted with DCM and washed with water, the organic phase dried (Na2504), filtered and the filtrate concentrated in vacuo. No further purification was necessary to afford 4,4-dimethylcyclohexyl methanesulfonate.

This compound has unique chemical properties. The synthetic route is as follows.

Method A: To a solution of 4,4-dimethylcyclohexanol (100 mg, 0.78 mmol) and Et3N (201 mg, 1.56 mmol) in CH2C12 (2 mL) was added methanesulfonyl chloride (178 mg, 1.56 mmol) at 0C and the reaction mixture was stirred at rt for 2 h before it was quenched with water and was extracted with CH2C12. The organic layer was washed with brine, separated, dried, filtered and concentrated to afford 4,4-dimethylcyclohexyl methanesulfonate which was used without further purification. To a solution of 7-nitrophthalazin-l(2H)-one (Intermediate- 10, step-1 , 100 mg, 0.52 mmol) in THF (2 mL) was added NaH (41 mg, 1.02 mmol, 60% in mineral oil) at 0C and stirred for 15 minutes. Then a solution of 4,4-dimethylcyclohexyl methanesulfonate in THF (1 mL) was slowly added to the reaction mixture at 0C. Then the reaction mixture was heated at 80C for 6 h before it was quenched with water and was extracted with EtOAc. The organic layer was washed with brine, separated, dried, filtered and concentrated. The residue was purified by column chromatography to afford 180 mg of the title product/H NMR (300 MHz, DMSO d6): delta 9.27 (s, 1H), 8.59-8.56 (d, / = 8.7 Hz, 1H), 8.30 (s, 1H), 7.88-7.85 (d, / = 8.7 Hz, 1H), 4.97-4.93 (m, 1H), 2.08-1.99 (m, 2H), 1.72-1.67 (m, 2H), 1.57-1.43 (m, 4H), 1.04 (s, 3H), 0.99 (s, 3H).
