Benzoic acid, 4-(1-aminocyclopropyl)-, methyl ester, hydrochloride (1:1)

Step 2:To a solution of ER-886774-00 (1.63 g, 0.0085 mol) in ethyl acetate (10 mL) was added 2.0 M of hydrogen chloride in Ether (6.0 mL, 0.012 mol). After stirring for several minutes, the reaction mixture was concentrated to give the title compound (quantitative yield) as pale brown solid.To a cooled solution of methyl 4-(1-aminocyclopropyl)benzoate (D6) (100 g, 524 mmol) in ethyl acetate (500 ml) 4N HCl (g)/ethyl acetate solution (300 ml) was added and the resulting mixture was stirred at room temperature for 2 hours. Evaporated the solvent, the residue was recrystallized with petroleum ether/EtOAc to afford the title compound (D7) (68.7 g) as a white solid.Step 2:To a solution of ER-886774-00 (1.63 g, 0.0085 mol) in ethyl acetate (10 mL) was added 2.0 M of hydrogen chloride in Ether (6.0 mL, 0.012 mol).

Evaporated the solvent, the residue was recrystallized with petroleum ether/EtOAc to afford the title compound (D7) (68.7 g) as a white solid.To a cooled solution of methyl 4-(1-((tert-butoxycarbonyl)amino)cyclopropyl)benzoate (D5) (7.4 g, 25.4 mmol) in ethyl acetate (10 ml) HCl (g)/ethyl acetate (4N, 50 ml) was added the mixture was stirred at room temperature overnight. Evaporated the solvent, the residue was washed with petroleum ether to afford the title compound (D7) (5.3 g) as a white solid.
