A solution of 2,4-bis-benzyloxy-5-isopropyl-benzoic acid (Preparation B10) (0.451 g, 1.2 mmol), EDC (0.276 mg, 1.44 mmol), HOAt (0.196 mg, 1.44 mmol), triethylamine (0.5 ml, 3.6 mmol) and 5-chloro-2,3-dihydro-1H-isoindole (0.187 g, 1.2 mmol) (Preparation C3) in DMF (5 ml) was stirred at room temperature for 16 hours, then evaporated under vacuum. The crude material was dissolved in ethyl acetate and extracted twice with saturated NaHCO3, organics washed with water three times, then evaporated under vacuum to give 0.5 g of 2,4-bis-benzyloxy-5-isopropyl-phenyl)-(5-chloro-1,3-dihydro-isoindol-2-yl)-methanone. MS: [M+H]+ 512
