- [(Alkoxycarbonyl)oxy]alkyl esters of methyldopa. Alexander, Jose; Shih, Chung (Merck and Co., Inc. , USA). U.S. US 4426391 A 17 Jan 1984, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C101-77; A61K031-265. NCL: 424301000. APPLICATION: US 82-418326 15 Sep 1982. DOCUMENT TYPE: Patent CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 63 Methyldopa esters I (R, R1 = H, C1-C10 alkyl; R2 = C1-C10 alkyl) or their salts were prepd. as antihypertensives (no data). Thus, ICH2OCO2CH2CH2CHMe2 was added to a soln. of methyldopa deriv. II (Z = PhCH2O2C) and Et3N in ether and (Me2N)3PO and the mixt. was stirred for 24 h at room temp. The product ester was deprotected by hydrogenolysis over 10% Pd/C to give I (R = R1 = H, R2 = Me2CHCH2CH2), isolated as the acetate salt.Except for chemicals metioned above, 89838-67-5 and 22128-62-7 are also used. .
