Reaction Conditions

Reaction Steps

A solution of 3-fluorobenzaldehyde in dry methanol (84 μL, 476 mM) was added to a solution of (4-Amino-2-methyloxyphenyl)-carbamic acid ethyl ester (84 μL, 0.476 M in dry methanol). The resulting mixture was heated to 40° C. for 30 minutes. The solvent was evaporated in vacuo, and the remaining material was dissolved in 1,2-dichloroethane (1 mL). Sodium triacetoxyborohydrate (20 mg) was added, and the resulting mixture was kept at room temperature for 2 hours, under 2 periods of sonication for 10 minutes, respectively. The reaction mixture was filtered through silica gel (500 mg), and the column was washed with 1,2-dichloroethane (3 mL). The solvent was evaporated in vacuo yielding the title compound (5.7 mg, 45%).
