Procedure
A solution of 4-methoxybenzenemethanamine (72.7 g) and triethylamine (83.6 ml) in CH2Cl2 (750 ml) was cooled on an ice-bath. Phenylchloroformate (91.4 g) was added dropwise and the reaction mixture was stirred at RT. The reaction mixture was washed three times with water and the precipitate was filtered off. The organic layer was separated, washed three times with a 5% aqueous NaHCO3 solution, dried (MgSO4), filtered and the solvent was evaporated. The precipitate was stirred in boiling diethyl ether (300 ml), filtered off and dried, yielding 84.4 g (65.5%) of phenyl [(4-methoxyphenyl)methyl]carbamate (interm. 2).
