Reaction Steps

A mixture of tert-butyl ((1S,2R)-2-((6-(2,6-difluoro-3-methoxyphenyl)quinazolin-2-yl)amino)cyclopentyl)carbamate (21 mg, 0.045 mmol) and 4M HCl in Dioxane (0.5 mL) in dichloromethane (1 mL) was stirred at room temperature for 16 h. LC-MS indicated complete consumption of SM. The reaction mixture was concentrated and used without further purification in the next step.
