Participants

Reaction Steps

To a mixture of saturated sodium bicarbonate (20 mL), ethyl acetate (20 mL) and 2-(3-(5-amino-3-tert-butyl-1H-pyrazol-1-yl)naphthalen-1-yl)acetamide (300 mg, 0.931 mmol) was added Troc-Cl (296 mg, 1.40 mmol). The mixture was stirred vigorously overnight. The mixture was diluted with ethyl acetate (30 mL) and the organic phase was separated, washed with 5% citric acid (30 mL) and brine (30 mL), dried (Na2SO4) and concentrated in vacuo to give a solid which was triturated with ethyl acetate and filtered to provide 2,2,2-trichloroethyl 1-(4-(2-amino-2-oxoethyl)naphthalen-2-yl)-3-tert-butyl-1H-pyrazol-5-ylcarbamate (241 mg, 52% yield). MS (ESI) m/z: 499.0 (M+H+).
