Procedure

To a solution of (7-tert-butyl-3,3-dimethyl-2,3-dihydrobenzo[b]furan-5-yl) carboxylic acid chloride (450 mg, 1.69 mmol) in CH2Cl2 (10 mL) is added in a single portion n-propylamine (2 mL). After the exothermic reaction subsides, the mixture is evaporated and suspended in 1N HCl (10 mL). The insoluble material is filtered and crystallized from isopropanol/H2O, to yield N-propyl (7-tert-butyl-3,3-dimethyl-2,3-dihydrobenzo[b]furan-5-yl)carboxamide as white needles.
