Yield:-

Reaction Conditions:

with 1,8-diazabicyclo[5.4.0]undec-7-ene in acetonitrile

Steps:

1 Preparation of Methyl 2,6-dimethoxybenzoate
EXAMPLE 1 Preparation of Methyl 2,6-dimethoxybenzoate A solution containing 2,6-dimethoxybenzoic acid (5.0 g, 27.5 mmol), DBU (4.2 g, 27.5 mmol), DMC (50 mL), and acetonitrile (50 mL) was circulated at 20 mL/min by a pump through a Milestone ETHOS-CFR continuous-flow reactor, which had been preheated to 160° C. at 20 bar by microwave irradiation. The reaction mixture was analyzed by HPLC after each cycle (6 minutes microwave irradiation). The yield of methyl 2,6-dimethoxybenzoate after two cycles (12 minutes microwave irradiation time) as determined by HPLC was 99% conversion. The reaction mixture was concentrated under vacuum. The residue was diluted with EtOAc (100 mL) and H2O (80 mL).
