Prepared using General Procedure 1. To a stirring solution of (R)-5-hydroxy-5,6,7,8-tetrahydronaphthalene-1-carbonitrile INT-2 (79.1 mg, 0.46 mmol) in EtOH (2 mL) was added hydroxylamine hydrochloride (34.9 mg, 0.50 mmol) and sodium bicarbonate (42.2 mg, 0.50 mmol). The mixture was heated at 70° C. for 18 h. The product was purified by chromatography (MeOH/DCM) to provide 27.3 mg (29%) (R)-N,5-dihydroxy-5,6,7,8-tetrahydronaphthalene-1-carboximidamide INT-4 as a white solid. LCMS-ESI (m/z) calculated for C11H11NO: 173.2; found 174.1 [M+H]+, 156.1 [M−NH4]+, tR=2.60 min.(S)-N,5-dihydroxy-5,6,7,8-tetrahydronaphthalene-1-carboximidamide INT-5 was prepared in an analogous fashion from (S)-5-hydroxy-5,6,7,8-tetrahydronaphthalene-1-carbonitrile INT-3.
