Procedure

2.0 g of (R)-2-amino-1,1-diphenyl-1-propanol, 1.47 g of 2-hydroxy-5-nitrobenzaldehyde and 30 ml of methanol were mixed, and the mixture was stirred at 80° C. for 1 hour. Thereafter, the mixture was cooled to 20° C. and the deposited crystals were collected by filtration. The collected crystals were washed with methanol and dried to give 3.22 g of (R)-N-(5-nitrosalicylidene)-2-amino-1,1-diphenyl-1-propanol. Yield 97.2%
