Procedure
Reduction 3-fluorobenzaldehyde O-methyloxime with sodium cyanoborohydride as described in the preparation of compound 3-B gave the title hydroxylamine as a clear oil (60% yield). 1HNMR 400 MHz (CDCl3) δ (ppm): 3.50 (3H, s, OCH3), 4.04 (2H, s, NCH2), 5.75 (1H, broad s, NH), 6.95-7.32 (4H, m, aromatics). The hydrochloride salt was obtained as a white solid: mp 130-131° C. (dec.). Anal. calcd for C8H10FNO—HCl: C, 50.14; H, 5.78; N, 7.31. Found: C, 50.10; H, 5.73; N, 7.38.
