Reaction Steps

tert-Butyl 2-(4-chlorophenyl)cyclopropylcarbamate (51.9 mg, 0.1938 mmol) was dissolved in Dichloromethane (1 ml) and 4M HCl solution in dioxane (0.4846 ml, 1.938 mmol) was added. The mixture was stirred for 3 hours at ambient temperature, during which time a white solid precipitated out of solution. The crude mixture was concentrated and chased with EtOAc (2×10 ml). The residual fine solid was dried under high vacuum to provide 39.2 mg of the title compound as a solid (99%).
