実験手順
10-[1-(1-Pyrrolidinyl)-2-propyl]-2-phenothiazinecarbonitrile hydrochloride, L series (5 g) is added to a solution of potassium hydroxide (1.75 g) in glycol (30 cc), and the mixture is stirred for 4 hours under reflux. After being cooled, the yellow solution obtained is diluted with acetone (75 cc) and a 3N solution (5 cc) of hydrochloric acid in ethyl ether, filtered and diluted again with acetone (75 cc) and a 3N solution (5 cc) of hydrochloric acid in ethyl ether. After priming, the mixture is left to crystallize for 16 hours at a temperature in the region of 5° C. The solid obtained is drained, washed with ethyl ether (10 cc) and dried under reduced pressure (5 mm Hg; 0.7 kPa) at 40° C. 10-[1-(1-Pyrrolidinyl)-2-propyl]-2-phenothiazinecarboxylic acid hydrochloride, L series (2.9 g) is thereby obtained in the form of a pale yellow solid, m.p. 200-210° C. (melts forming a paste).
