実験手順

Reduction of 4-cyanobenzaldehyde O-methyloxime with sodium cyanoborohydride as described in the preparation of Compound 44-B gave the title hydroxylamine as a clear oil (75% yield). 1HNMR 400 MHz (CDCl3) δ (ppm): 3.48 (3H, s, OCH3), 4.09 (2H, s, NCH2), 7.48 (2H, m, aromatics), 7.63 (2H, m, aromatics). The hydrochloride salt was obtained as a white solid: mp 168° C. (dec.). Anal. calcd. for C9H10N2O—HCl: C, 54.41; H, 5.58; N, 14.10. Found: C, 54.44; H, 5.62; N, 13.94.
