Procedure

To a stirred brown solution of [3-(2,6-dioxo-piperidin-3-yl)-2-methyl-4-oxo-3,4-dihydro-quinazolin-5-ylmethyl]-carbamic acid tert-butyl ester (10.4 g, 25.9 mmol) in methanol (108 mL) and methylene chloride (108 mL), was added 2 M HCl in ether (304 mL), and the mixture was stirred overnight. Solvent was evaporated, and the residue was stirred in ether (200 mL) for 2 hours. The suspension was filtered to give 3-(5-aminomethyl-2-methyl-4-oxo-4H-quinazolin-3-yl)-piperidine-2,6-dione hydrogen chloride as a light yellow solid (8.9 g, 102% crude yield). The product was used in the next step without further purification.
