実験手順

Prepared using General Procedure 1. To 2-((tert-butyldimethylsilyloxy)methyl)isonicotinonitrile INT-71 (0.169 g, 0.68 mmol) in EtOH (8 mL) was added hydroxylamine hydrochloride (0.142 g, 2.0 mmol) and Na2CO3 (0.216 g, 2.0 mmol) and the reaction mixture was heated at 85° C. for 12 h. Once cooled to room temperature, the reaction mixture was filtered using EtOH to rinse the filter cake. The filtrate was concentrated under reduced pressure and washed with EA and brine. The combined organic layers were dried over MgSO4, filtered, and concentrated to produce 0.191 g (100%) of 2-((tert-butyldimethylsilyloxy)methyl)-N-hydroxyisonicotinimidamide INT-72 as a light yellow oil. LCMS-ESI (m/z) calculated for C13H23N3O2Si: 281.4; found 282.1 [M+H]+, tR=2.76 min (Method 1). 1H NMR (400 MHz, (CD3)2SO) δ 8.50 (dd, J=5.2, 0.7, 1H), 7.74 (dd, J=1.6, 0.7, 1H), 7.51 (dd, J=5.2, 1.7, 1H), 5.98 (s, 2H), 0.96-0.89 (m, 9H), 0.14-0.07 (m, 6H).
