Reaction Steps

(4-Methoxyphenyl)methanamine (1.0 g) in ethanol (10 ml) was treated with 5% Rh—Al2O3 (99.8 mg, 0.048 mmol) under H2 atmosphere (500 psi) at 50° C. for 16 hours. Additional 5% Rh—Al2O3 (0.4 g) was added. The resulting mixture was stirred under H2 atmosphere (500 psi) at 60° C. for 2 hours. The insoluble material was filtered off and the filtrate was concentrated to provide a mixture of cis and trans product as an oil, which was used in the next step without further purification.
