Versuchsvorschrift

DMF (1 drop) was added to a suspension of 5-{[(3-chlorophenyl)methyl]oxy}-2-methylbenzoic acid from the preparation of Intermediate 85 as described above (200 mg, 0.72 mmol) and oxalyl chloride (95 ul, 1.08 mmol, 1.5 eq) in DCM (5 ml). The resulting mixture was stirred at room temperature for 1 hour. The reaction mixture was then evaporated to dryness and azeotroped with toluene (2×50 ml). The organic layer was separated, dried and evaporated in vacuo to afford the title compound as a yellow solid, 213 mgs. No further purification carried out. LCMS sample dissolved in methanol, MS (ES+) m/z 291 [M+H]+ (C16H1535ClO3), corresponding to methyl ester generated from acid chloride.
