Procedure

A mixture of 5-[(1R)-1-amino-2-phenylethyl]-7-(2-hydroxyphenyl)-1,4-dihydro-2H-pyrido[2,3-d][1,3]oxazin-2-one hydrochloride (0.014 g, 0.035 mmol), which was obtained in Example 18-4, in acetonitrile (3.0 mL) was heated at reflux for 2 hrs. The resulting mixture was concentrated under reduced pressure. The residue was dissolved in 1,4-dioxane (1.0 mL), treated with 4N HCl solution in 1,4-dioxane (0.5 mL), and concentrated under reduced pressure. The residue was triturated with acetonitrile, and dried under reduced pressure to give 2-[(1R)-4-amino-1-benzyl-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-yl]phenol hydrochloride as a white solid (0.010 g, yield; 80%).
