Steps:

12.B N-{3-[5-(4-Fluorophenylmethyl)-2-thienyl]-1-methyl-2-propynyl}-N-hydroxyurea
EXAMPLE 12B N-{3-[5-(4-Fluorophenylmethyl)-2-thienyl]-1-methyl-2-propynyl}-N-hydroxyurea Using the procedures described in Example 1C, the compound resulting from Example 12A (13.3 g, 49.0 mmol) was converted to the alcohol intermediate in a yield of 9.16 g (71%). In a manner analogous to the procedures described in Example 1D, the alcohol intermediate from above was converted to the title compound in 33% yield. m.p. 141°-142° C.
