PCT No. PCT/GB96/02337 Sec. 371 Date Feb. 19, 1998 Sec. 102(e) Date Feb. 19, 1998 PCT Filed Sep. 24, 1996 PCT Pub. No. WO97/12864 PCT Pub. Date Apr. 10, 1997The invention relates to a process for the preparation of 2-(pyrid-2-yloxymethyl)phenylacetates of formula (I) useful as intermediates for agricultural pesticides, which comprises reacting a 2-pyridine of formula (II), wherein L is a leaving group and A, D and m are as defined in the description with a compound MO-CH2R where M is a metal atom and R is the residue of a metal salt of phenylacetic acid. It also includes the compounds MO-CH2R, a process for their preparation and a "one-pot" process for the preparation of 2-(pyrid-2-yloxymethyl) phenylacetates from 3-isochromanone.
