(4,4-difluorocyclohexyl)methyl methanesulfonate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Mesylate 142 (0.9 g, 3.94 mmole), 3-hydroxybenzaldehyde (0.577 g, 4.73 mmole), K2CO3 (0.817 g, 5.91 mmole) and NMP (5 ml) were heated at 70° C. overnight. H2O (30 ml) and hexanes (50 ml) was added and stirred for 1 hr. The organic layer was dried over Na2SO4 and evaporated. Purfication by flash chromatography (20% ether/hexanes gradient) gave 3-((4,4-difluorocyclohexyl)methoxy)benzaldehyde (143) as ah oil. Yield (0.559 g, 56%): 1H NMR (400 MHz, DMSO-d6) δ 9.95 (s, 1H), 7.51-7.46 (m, 21H), 7.41-7.40 (m, 1H), 7.25 (dt, J=6.8, 2.8 Hz, 1H), 3.91 (d, J=6.0 Hz, 2H), 2.06-1.98 (m, 5H), 1.89-1.73 (m, 5H), 1.37-1.27 (m, 2H). The organic layer was dried over Na2SO4 evaporated

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: (4,4-Difluorocyclohexyl)methanol (0.7 g, 4.11 mmole) was stirred in CH2Cl2 (5 ml) and cooled in an ice bath. TEA (0.499 g, 4.93 mmoles) was added followed by methanesulfonyl chloride (0.518 g, 4.52 mmoles). Stirring was continued overnight while allowing to warm to room temp. 1.0 N HCl (30 ml) and CH2Cl2 (30 ml) was added and stirred for 5 min. The organic layer was dried over Na2SO4 and evaporated giving (4,4-difluorocyclohexyl)methyl methanesulfonate (142) as an oil. Yield (0.92 g, 98%): 1H NMR (400 MHz, DMSO-d6) δ 4.06 (d, J=6.4 Hz, 2H), 3.14 (s, 3H), 2.04-1.95 (m, 2H), 1.88-1.70 (m, 5H), 1.29-1.19 (m, 2H). cooled in an ice bath stirred for 5 min The organic layer was dried over Na2SO4 evaporated
