Reaction Steps

2-Amino-5-chlorobenzoic acid methyl ester (1.85 g, 10.0 mmol) was treated with 1-napthaldehyde (1.56 g, 10.0 mmol) and sodium triacetoxyborohydride (4.23 g, 20.0 mmol) in 1,2-dichloroethane as described in general procedure E to give 5-chloro-2-[(napthalen-1yl-methyl)-amino]-benzoic acid methyl ester (2.54 g, 78%). This methyl ester (2.0 g, 6.13 mmol) was treated with LiOH (2 eq, 1N aqueous solution) according to the general procedure C gave 5-chloro-2-[(napthalen-1yl-methyl)-amino]-benzoic acid (1.64 g, 86.0%).
