  The present invention provides an industrially advantageous process for producing a steroid C 17,20 lyase inhibitor represented by the general formula (I); and a Reformatsky reagent in a stable form suitable for the process. In the present invention, a compound represented by the general formula (I) is produced by reducing a specific β-hydroxy ester compound derivative or a salt thereof obtained from a specific carbonyl compound in a Reformatsky reaction in the presence of a metal hydride complex and a metal halide, and then subjecting it to a ring-closing reaction. In the above Reformatsky reaction, it is useful to use a stable solution of a compound represented by the general formula BrZnCH 2 COOC 2 H 5 or a crystal of the compound which is represented by the formula (BrZnCH 2 COOC 2 H 5 .THF) 2 .

  本发明提供了一种工业上有利的生产类固醇C17,20裂解酶抑制剂的过程，该抑制剂由通式（I）表示；以及适用于该过程的稳定形式的Reformatsky试剂。在本发明中，通过在金属氢化物复合物和金属卤化物的存在下还原从特定羰基化合物中获得的特定β-羟基酯化合物衍生物或其盐，并随后将其进行环合反应，从而产生通式（I）表示的化合物。在上述Reformatsky反应中，使用通式BrZnCH2COOC2H5表示的化合物的稳定溶液或者由式（BrZnCH2COOC2H5.THF）2表示的化合物的晶体是有用的。
