Participants

Reaction Conditions

Reaction Steps

Methylamine gas was bubbled into a solution of 3-(tert-butoxycarbonylamino)-3-(4-chlorophenyl)propyl methanesulfonate (Intermediate 31) (70 mg, 0.19 mmol) in THF (5 mL) at 22° C. over a period of 5 minutes. The mixture was sealed into a microwave tube. The reaction was heated to 125° C. for 30 minutes in the microwave reactor and cooled to ambient temperature. The mixture was evaporated and the residue was purified by flash silica chromatography, elution gradient 4 to 8% (10:1 MeOH/conc. NH3 (aq)) in DCM. Pure fractions were evaporated to dryness to afford tert-butyl 1-(4-chlorophenyl)-3-(methylamino)propylcarbamate (52 mg, 90%) as a colourless oil.
