tert-butyl N-[(4,4-difluorocyclohexyl)methyl]carbamate

Conditions: temp:0.00; pressure:0.00; stir:

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

Procedure: A solution of EXAMPLE 396A (3 g) in dichloromethane (35 mL), trifluoroacetic acid (15 mL), and triethylsilane (1 mL) was stirred for 2 hours. The solution was concentrated, then condensed from toluene, and left under high vacuum for 24 hours. The semi-solid was taken up in ether/hexane and filtered to give the title compound as its TFA salt. The solution was concentrated condensed from toluene filtered

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

Procedure: tert-Butyl [(4,4-difluorocyclohexyl)methyl]carbamate (505 mg, 2.03 mmol) was stirred in 5 mL of 1M HCl/AcOH at rt for 2 h. The solvent was evaporated. The residue was washed with ether, filtered and dried. Yield: 330 mg (88%). 1H NMR (400 MHz, METHANOL-D4): δ 1.28-1.40 (m, 2H), 1.71-1.82 (m, 2H), 1.84 (d, J=3.12 Hz, 2H), 1.86-1.89 (m, 1H), 2.03-2.15 (m, 2H), 2.85 (d, J=7.03 Hz, 2H).
