반응 단계

A stirred solution of the product from Step 4 (2.00 g, 0.00711 mol), (R)-(+)-1-phenylpropylamine (1.06 g, 0.00784 mol), N-methylmorpholine (1.69 ml, 0.0154 mol) and isopropanol (13.3 ml) was refluxed, under nitrogen, until the reaction was shown to be complete by TLC (28 hours). It was then concentrated and the residue chromatographed on silica gel with 1 to 4% MeOH-CHCl3. A solution of the product thus obtained in MeOH-EtOAc was decolorized with Darco (activated charcoal) and crystallized from EtOAc-hexane to give 1.02 g, m.p. 109°-111° C. and 0.120 g, m.p. 107°-113° C. of the titled product.
