2-Chloro-10-[3-[4-(2-chloroethyl)piperazin-1-yl]propyl]phenothiazine → (R)-1-(1-methylethylamino)-3-[4-[2-[4-[3-(2-chloro-10H-phenothiazin-10-yl)propyl]piperazin-1-yl]ethoxy]phenoxy]-2-propanol, trihydrochloride

Participants

Reaction Steps

Using the conditions outlined in method A, 11.7 g of 1-[3-(2-chloro-10H-phenothiazin-10-yl)propyl]-4-(2-chloroethyl)piperazine was reacted with 7.5 g of (R)-1-(4-hydroxyphenoxy)-3-(1-methylethyl)amino-2-propanol to give, after recrystallization from methanol-ethyl acetate and from methanol-ethanol, the trihydrochloride salt of (S)-1-(1-methylethylamino)-3-[4-[2-[4-[3-(2-chloro-10H-phenothiazin-10-yl)propyl]piperazin-1-yl]ethoxy]phenoxy]-2-propanol, trihydrochloride, mp 251.5°-253°; [α]D25 +10.37° (c, 1.0, methanol).
