Reaction Conditions

Reaction Steps

HCl (4M) in 1,4 dioxane (1.674 mL, 6.69 mmol) was added to tert-butyl 3-amino-1-(4-chlorophenyl)-3-oxopropylcarbamate (Intermediate 106) (200 mg, 0.67 mmol) in DCM (20 mL) at 20° C. The resulting solution was stirred at 20° C. for 4 hours. The reaction mixture was evaporated and was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH and pure fractions were evaporated to dryness to afford 3-amino-3-(4-chlorophenyl)propanamide (46.0 mg, 34.6%) as a white solid.
