The title compds. [I; R1, R2 = H, (di)(alkyl)aminocarbonyl, PO(OH)2, (halo)alkanoyl, alkenoyl] are prepd. as antiestrogens, and are useful for the treatment of estrogen receptor-pos. tumors (no data). Thus, 2-(2-fluoro-4-methoxyphenyl)-2-propanol (II; prepn. given) was stirred with TiCl3 in dry dimethoxyethane, followed by the addn. of LiAlH4 and more II, to give I (R1 = R2 = OMe), which was ...
