A method for acylating a hexakis (arylmethyl) hexaazaisowurtzitane (WB6) by reductively removing the arylmethyl groups in the presence of an acylating agent, characterized by contacting a WB6 (a) with a heterogeneous system reduction catalyst (b) in the presence of an acylating agent (c) and a reducing agent (d) in a solvent (e) for the WB6 (a) to reductively remove the arylmethyl groups from the WB6 (a) and acylate the same, and by preventing the WB6 (a) and the catalyst (b) from being contacted with each other when at least either of the acylating agent (c) and the reducing agent (d) is not present. In this method, the decomposition of the WB6 skeleton, which readily occurs in the beginning of the acylation of the WB6 as a starting material, can be highly effectively inhibited. This method can hence stably produce a tetraacylhexaazaisowurtzitane derivative in a high yield and is industrially advantageous.
