The Uses of Methyl 3-amino-4-methylbenzoate

Methyl 3-Amino-4-methylbenzoate is used as a reagent in the synthesis of perfluoroalkylated indoles which are very useful in drug development. It was also used in the preparation of 4-(pyrimidin-2-ylamino) benzamide derivatives which are designed as inhibitors of hedgehog signalling pathway (target of cancer treatment).

What are the applications of Application

Methyl 3-amino-4-methylbenzoate can be used for:
To prepare the methyl 4-methyl-3-((4-(proparg-1-yloxy)benzyl)amino)benzoate, 4-proparg-1-yloxybenzaldehyde (16) and methyl 3-amino-4-methylbenzoate were reacted according to the method IA.
Synthesis of Methyl 4-methyl-3-((4-(2-methylthiazol-4-yl)benzoyl)amino)benzoate
Synthesis of 4-Methyl-3-((4-(2-methylthiazol-4-yl)benzoyl)amino)benzamide

Synthesis of methyl 3-(4-hydroxy-6-methyl-2-oxopyridin-1 (2H)-yl)-4-methylbenzoate
Synthesis of (5-Carbomethoxy-2-methylphenyl)(4-hydroxypheny)diazene: To a solution of 6N HC1 (6 mL) was added methyl 3-amino-4-methylbenzoate (1.62 g, 10.0 mmol). The solution was cooled in an ice-bath, and was diazotized by adding sodium nitrite (0.9 g, 12.0 mmol). To a cold solution of phenol in 21% aqueous NaOH solution (6 mL) was added diazotized solution slowly. After 20 min, the solution was acidfied by adding 4 N aqueous HC1 and was poured into the cold water, filtered, and washed with water. Recrystallization from ethanol gave the product (2.0 g, 74%) as red crystals, mp 181.3-182.2 °C.

Preparation

Synthesis of Methyl 3-amino-4-methylbenzoate: Nitro ester Methyl 4-methyl-3-nitrobenzoate (80 g, 0.410 mol) was subjected to hydrogenation in a Parr shaker in MeOH using Raney Ni as the catalyst (5 g, 20 mol %) at 50 psi for 8 hours. The catalyst was filtered off, washed thoroughly with MeOH and the combined filtrates concentrated under reduced pressure to furnish a yellow solid (65.0 g). Yield : 96% Mp : 114-5°C (lit.14 Mp 116°C)

Definition
