実験手順

A solution of 200 mg (0.313 mmole) of (3R, 5S)-5-[(1S)-1{N-[2(R)-benzyl-3-(morpholinocarbonyl)propionyl]-3-(4-thiazolyl)-L-alanyl}amino-2-cyclohexylethyl]-3-methyldihydrofuran-2(3H) -one [prepared as described in Preparation 21(a) above] in 2 ml of methanol was added, whilst ice-cooling, to 2.5 ml of a 40% by volume methanolic solution of methylamine, and the mixture was allowed to stand at room temperature for 1 hour. At the end of this time, any excess of the methylamine and the methanol were removed by distillation under reduced pressure. The resulting residue was dissolved in 4 ml of ethyl acetate, and the solution was allowed to stand overnight at room temperature to deposit crystals. These were collected by filtration to afford 150 mg of the title compound as white crystals, melting at 130°-132° C.
