Use
Crystallise R-apomorphine from CHCl3 and a little pet ether, also from Et2O with 1 mol of Et2O which it loses at 100o. It sublimes in a high vacuum. It is white but turns green in moist air or in alkaline solution. UV: max 336, 399 (98% EtOH). The di-O-methylether is an oil b 175o/high vacuum, whose picrate crystallises from MeOH and has m 140o (dec). The di-O-acetate crystallises from EtOAc/pet ether with m 127-128o, [] D -88o (c 1, 0.1 N HCl). The di-O-benzoyl derivative has m 156-158o (from EtOH) and []D +43.44o (c 3.3, CHCl3). [Pachorr et al.
