I were prepared by treating α-phenoxy-, α-o-chlorophenoxy- and α-(o-methoxyphenoxy)isobutyryl chloride with the appropriate amino alcs.Thus, a solution of α-(o-chlorophenoxy)isobutyric acid in 500 ml. anhydrous C6H6 was added to a solution containing 133 g. N,N-dimethylaminoethoxyethanol and 202 g. of Et3N in 500 ml. of anhydrous C6H6, the mixture was boiled 4 hrs. with continuous stirring; the Et3N.HCl was filtered off; the solvent was then evaporatedI (R1 = Cl, R2 = (CH2)2O(CH2)2NMe2 b. 130-5°.Citrate salt was prepared by addition of an alc. solution of citric acid to the product.Similarly prepared were the following I [R1, R2 (X = piperidino, Y = morpholino), b.p., and m.p. citrate salt given]: H, (CH2)2NMe2, 93°, 98-9°;H, (CH2)2NEt2, 105-7°, 134-5°;H, (CH2)2X, 122-5°, 75-8°;H, (CH2)2Y, 127-30°, -- (hydrochloride 143-5°); H, (CH2)2O(CH2)2NMe2 (II), 125-8°, 84-5°; H, (CH2)2O(CH2)2NEt2, 117-20°, 83-4°; H, (CH2)2O(CH2)2Y, 125-30°, 100-2°; Cl, (CH2)2NMe2, 122-3°, 88-90°; Cl, (CH2)2NEt2, 124-6°, 131-3°; Cl, (CH2)2X, 128-32°, 62-6°; Cl, (CH2)2Y, 140-2°, 85-7°; Cl, (CH2)2O(CH2)2NEt2, 134-8°, 72-4°; Cl, (CH2)2O(CH2)2Y, 136-9°, 75-7°; MeO, (CH2)2NMe2, 115-18°, 86-8°; MeO, (CH2)2NEt2, 126-8°, 106-8°; MeO, (CH2)2X, 132-4°, 54-6°; MeO, (CH2)2Y, 130-5°, 100-2°; MeO, (CH2)2O(CH2)2NMe2, 129-33°, 70-1°; MeO, (CH2)2O(CH2)2NEt2 (III), 133-7°, 80-1°; MeO, (CH2)2O(CH2)2Y, 140-5°, 77-9°.Antitussive properties were found in II and III.
